GENERAL INFORMATION

UNIPROT
COMMENTARY
LITERATURE
malfunction
-
loss-of-function mutations and RNA interference-mediated reduction of DPMS1 expression in Arabidopsis causes a wrinkled seed coat phenotype and most remarkably enhanced hypersensitivity to ammonium that is manifested by extensive chlorosis and a strong reduction of root growth
metabolism
-
dolichyl phosphate mannose synthase is a key enzyme in the O-glycosylation pathway
physiological function
synthetic construct
-
high level of expression of (GlcNAc-beta-(1,4)-GlcNAc) 1-4-beta-GlcNAc-NeuAc glycans on the external surface of the capillary endothelial cells overexpressing DPMS. Increased cellular proliferation and accelerated healing of the wound induced by mechanical stress of the DPMS-overexpressing clone unequivocally supports a role of DPMS in angiogenesis
physiological function
-
overexpression of DPMS accelerates angiogenesis, a higher rate of cellular proliferation in DPMS overexpressing cells compared to the pEGFP-N1 vector and the parental cells
physiological function
-
elevated activity of overexpressed Saccharomyces cerevisiae dolichyl phosphate mannose synthase enhances biocontrol abilities of Trichoderma atroviride
physiological function
-
overexpression of DPMS1 in Arabidopsis thaliana results in disorganized stem morphology and vascular bundle arrangements, wrinkled seed coat, and constitutive ER stress response

-
mutant enzymes containing successive deletions or mutations of the hydrophobic region exhibit decreased transferase activity in vitro compared to the wild type enzyme, but the sequence is not essential for growth or for protein glycosylation. Although deletion of the entire hydrophobic region results in a soluble protein, mutant proteins containing 3 or 8 hydrophobic residues are still membrane-associated
additional information
-
DPM synthase mutants have an aberrant cell wall composition and ultrastructure. Mutant is oversensitive to Calcofluor white, an agent interacting with the cell wall chitin. Chemical analysis of the cell wall alkali-insoluble fraction indicates an increased amount of chitin and changes in the quantity of beta1,6- and beta1,3-glucan in dpm1-6 mutants. Cell wall defect is suppressed by an increased dolichol availability caused by the RER2 (cis-prenyl transferase-encoding) gene overexpression and subsequent upregulation of DolPPGlcNAc2 synthesis. This is concomitant with an increase in glycosylation and stability of the plasma membrane protein Gas1 and rearrangement of the cell wall components

-
inhibition of DPMS is a promising strategy for the development of anti-trypanosomal agents. Thiazolidinones [(5Z)-5-[[4-(benzyloxy)phenyl]methylidene]-4-oxo-2-thioxo-1,3-thiazolidin-3-yl]acetic acid, [(5Z)-5-[[3,4-bis(benzyloxy)phenyl]methylidene]-4-oxo-2-thioxo-1,3-thiazolidin-3-yl]acetic acid and [(5Z)-5-[(2-hydroxyphenyl)methylidene]-4-oxo-2-thioxo-1,3-thiazolidin-3-yl]acetic acid in particular are promising candidates for further development because of their respective activities against trypanosomal DPMS and GPI anchor biosynthesis
