1.14.11.4 additional information the endoplasmic reticulum complex including SC65 and prolyl 3-hydroxylase 3affects the activity of lysyl-hydroxylase 1 potentially through interactions with the enzyme and/or cyclophilin B. Loss of Sc65 in the mouse results in instability of this complex, altered collagen lysine hydroxylation and cross-linking leading to connective tissue defects that include low bone mass and skin fragility, while it has no effect on prolyl 3-hydroxylation. CRTAP, a non-enzymic member of the Leprecan family of proteins which includes Synaptonemal Complex 65 (SC65) and the prolyl 3-hydroxylases (P3H1, P3H2 and P3H3), is an essential third subunit of a complex with prolyl 3-hydroxylase 1 (aka LEPRECAN) and cyclophilin B (CYPB) in the endoplasmic reticulum, forming the so-called collagen prolyl 3-hydroxylation complex Mus musculus

General Information

EC Number General Information Comment Organism
1.14.11.4 malfunction mice with loss of function of Leprel2 (encoding P3H3) have the same loss of tissue type I collagen lysine-hydroxylation as that observed in the Sc65 knockout mice. Loss of Sc65 in the mouse results in instability of this complex, altered collagen lysine hydroxylation and cross-linking leading to connective tissue defects that include low bone mass and skin fragility, while it has no effect on prolyl 3-hydroxylation. Sc65KO mouse generation and confirmation of bone loss phenotype, overview Mus musculus
1.14.11.4 metabolism the endoplasmic reticulum complex including SC65 and prolyl 3-hydroxylase 3 affects the activity of lysyl-hydroxylase 1 potentially through interactions with the enzyme and/or cyclophilin B. The prolyl-hydroxylase complex in the endoplasmic reticulum controls lysyl-hydroxylase activity during collagen synthesis. SC65/LH1/P3H3 are interlinked within a protein complex in the endoplasmic reticulum Mus musculus
1.14.11.4 physiological function in the endoplasmic reticulum, specific proline and lysine residues of newly translated procollagen chains are modified by prolyl- and lysyl-hydroxylases, respectively. These enzymes share a highly conserved catalytic 2-oxoglutarate, ascorbate- and Fe(II)-dependent dioxygenase domain Mus musculus
