The reaction direction shown, that is, A + B ↔ C + D versus C + D ↔ A + B, is in accordance with the Enzyme Commission system.
Most BioCyc compounds have been protonated to a reference pH value of 7.3, and some reactions have been computationally balanced for hydrogen by adding free protons. Please see the PGDB Concepts Guide for more information.
Mass balance status: Balanced.
Enzyme Commission Primary Name: dolichyl-phosphate-mannose--protein mannosyltransferase
Enzyme Commission Synonyms: dolichol phosphomannose-protein mannosyltransferase, protein O-D-mannosyltransferase
Standard Gibbs Free Energy (ΔrG'° in kcal/mol): -95.1897 [Latendresse13]
Enzyme Commission Summary:
The enzyme transfers mannosyl residues to the hydroxy group of serine or threonine residues, producing cell-wall mannoproteins. It acts only on long-chain α-dihydropolyprenyl derivatives, larger than C35.
