Standard Gibbs Free Energy (ΔrG'° in kcal/mol): 9.480011 [Latendresse13]
Enzyme Commission Summary:
Also acts on (3S,4R)-ketose 1-phosphates. The yeast and bacterial enzymes are zinc proteins. The enzymes increase electron-attraction by the carbonyl group, some (Class I) forming a protonated imine with it, others (Class II), mainly of microbial origin, polarizing it with a metal ion, e.g. zinc.
