evolution

metabolism
-
in osteoarthritic human synovial fibroblasts, the enzyme expression is induced by TGF-beta via kinase ALK5, not ALK1, and Smad2/3P
physiological function
additional information
-
heterocomplex formation between mouse and human LH3, between human LH1 and LH3 and between human LH2 and LH3, low amount of complexes formed in vivo
evolution
-
LH3 belongs to the lysyl hydroxylase family of enzymes that has important roles in the biosynthesis of collagen
evolution
-
whereas in animals from sponges to humans the transfer of galactose to hydroxylysine in collagen is conserved, the mimivirus L230 enzyme transfers glucose to hydroxylysine, thereby defining another type of collagen glycosylation in nature. Utilization of glucose instead of the galactose found throughout animals as well as a bifunctional enzyme rather than two separate enzymes may represent a parallel evolutionary track in collagen biology

malfunction
-
disorders of LH3 with a unique phenotype causing severe morbidity as a result of feauters that overlap with collagen disorders; mutations in the LH3 gene cause connective tissue disorder
malfunction
reduction of lysyl hydroxylase 3 causes deleterious changes in the deposition and organization of extracellular matrix; reduction of lysyl hydroxylase 3 causes deleterious changes in the deposition and organization of extracellular matrix. Mutations in the human LH3 gene cause a severe connective tissue disorder with features that overlap with a number of collagen disorders
malfunction
-
although differential expression of LH2 (long) is associated with fibrotic conditions, there is no direct evidence that the increased Pyr cross-links in the overaccumulated collagen contribute definitively to fibrosis
malfunction
impairment of LH3 function significantly affects type I collagen fibrillogenesis
malfunction
-
PLOD2 knockdown prevents fibrillar collagen formation in breast tumors, decreased PLOD2 expression in breast cancer cells inhibits metastasis, also lung metastasis is significantly impaired by PLOD2 knockdown
malfunction
-
lack of LH3 prevents the formation of hydroxylysine linked Glc-Gal structures in collagen. Secretion of type IV collagen is blocked in embryos that lack LH3 catalyzed Glc-Gal-Hyl residues, and this disrupts formation of the basement membranes that support tissues e.g. blood vessels. Changes in the lysyl hydroxylase activity of LH3 affect the adiponectin level and modifications in mouse, its secretion and oligomer distribtion, phenotype, overview. Recombinant adiponectin produced in LH3-/- knockout fibroblasts cells does not form middle molecular weight and high molecular weight oligomers

lysyl hydroxylase 3 (LH3) is a post-translational modification enzyme with lysyl hydroxylase, collagen galactosyltransferase EC 2.4.1.50, and glucosyltransferase, EC 2.4.1.66, activities, LH3 is able to catalyze the three consecutive reactions required for the formation of unique hydroxylysine-linked carbohydrates, galactosylhydroxylysine and glucosylgalactosyl hydroxylysine, found in collagens and a few other proteins. The active sites for the different activities of the mutifunctional enzyme are localized separately in the C- and the N-terminal parts of the molecule. While the lysyl hydroxylase active site mediates retention of LH3 in the endoplasmic reticulum, the glucosyltransferase active site is required for the secretion of LH3 into the extracellular space

physiological function
-
lysyl hydroxylases are enzymes that catalyze the hydroxylation of lysine into hydroxylysine and, therefore, fulfill a crucial role in collagen modification and cross-linking. Lysyl hydroxylase 2b increases pyridinoline cross-links, making collagen less susceptible to enzymatic degradation
physiological function
lysyl hydroxylase (LH) catalyzes the hydroxylation of lysine residues in collagens, and contributes to the formation of more stable collagen cross-links; lysyl hydroxylase (LH) catalyzes the hydroxylation of lysine residues in collagens, and contributes to the formation of more stable collagen cross-links; lysyl hydroxylase (LH) catalyzes the hydroxylation of lysine residues in collagens, and contributes to the formation of more stable collagen cross-links

lysyl hydroxylase 3 glucosylates galactosylhydroxylysine residues in type I collagen in osteoblast culture, role of LH3 in bone physiology
physiological function
-
the lysyl 5S-hydroxylase, JMJD6 acts on proteins involved in RNA splicin. JMJD6 in human cells is self-hydroxylated at Lys111JMJD6 and Lys167JMJD6 to give lysyl 5S-hydroxylase. Self-hydroxylation of JMJD6 may play a regulatory role in modulating the hydroxylation status of proteins involved in RNA splicing
physiological function
-
in hypoxic breast cancer cells, hypoxia-inducible factor 1 activates transcription of the PLOD1 and PLOD2 genes encoding procollagen lysyl hydroxylases that are required for the biogenesis of collagen, which is a major constituent of the extracellular matrix. High PLOD2 expression in breast cancer biopsies is associated with increased risk of mortality. PLOD2 is critical for fibrillar collagen formation by breast cancer cells, increases tumor stiffness, and is required for metastasis to lymph nodes and lungs
physiological function
-
regulation of the posttranslational lysine modifications in the collagenous domain is the key event in determining the function of adiponectin, changes in the lysyl hydroxylase activity of LH3 affect the adiponectin level and modifications in mouse, its secretion and oligomer distribtion

site-directed mutagenesis, point mutation is introduced in the LH1 part of the expression construct comprising 40 amino acid residues of the C-terminal end of isozyme LH1, responsible for endoplasmic reticulum localization, fused to human cathepsin D and c-Myc-tagged, the exchange of the charged residue and deletion of 8 amino acids of the last 40 residues at the enzymes' C-terminal end has no effect on retention efficiency of the reporter protein, but deletion of the next 8 amino acid residues, leaving 24 residues, increases the secretion level of enzyme from the cell

naturally occurring mutation T1360G in a highly conserved region of exon 13 of isozyme LH1 in skin fibroblasts is predicted to lead to the W446G exchange in heterozygous Ehlers-Danlos syndrome type IVA, leads to loss of enzyme activity and causes the pathogenic effect probably due to incorect folding of isozyme LH1, structure-function analysis

LH3 knock-out embryos and embryonic fibroblasts indicate that the loss of hydroxylysine glycosylation prevents the assembly and secretion of type IV and VI collagens, LH mutant mice show ultrastructural alterations in their skin and muscle
additional information
LH-deficient mutant, deficiency of LH3 glycosyltransferase activity decreases cell growth and increases lethality; overexpression of LH3, increased hydroxylation of lysyl residues and increased galactosylation and glucosylation of hydroxylysyl residues; targeted disruption of isoform LH3 by siRNA causes a marked reduction of both glycosyltransferase activities. Overexpression of LH3 increases hydroxylation of lysyl residues and the subsequent galactosylation and glucosylation of hydroxylysyl residues. Treatment of cells in culture medium with a LH3 N-terminal fragment affects the cell behavior, rapidly leading to arrest of growth in a reversible manner

mice with targeted inactivation of the Plod1 gene for lysyl hydroyxylase 1 are flaccid and have gait abnormalities. About 15% of them die because of aortic rupture, and smooth muscle cells in non-ruptured Plod1-/- aortas show degenerative changes. Collagen fibrils in the Plod1-/- aorta and skin have an abnormal morphology. The lysyl hydrolase activity level in the Plod1-/- skin and aorta samples is 35-45% of that in the wild type. The hydroxylysine content is decreased in all the Plod1-/- tissues, ranging from 22% of that in the wild type in the skin to 75% and 86% in the femur and lung, respectively
