I suck at remembering which enzymes have vitamin "X" as a cofactor... i'm trying to simplify it now by just remembering the type of reaction catalyzed. Does this look about right? Any major things missing?

B1: dehydrogenases, transketolase
B2: FAD/FMN-related redox
B3: NAD/NADP-related redox
B5: CoA, fatty acid synthase
B6: decarboxylases, default answer if unsure [transamination, glycogen phosphorylase, cystathione synthesis, heme synthesis, etc.]
B7: carboxylases (minus vit. K)
B12: homocysteine methyltransferase, methylmalonyl-CoA mutase
Folic Acid: 1-carbon transfer
Vitamin C: hydroxylases
Vitamin K: gamma-carboxylation

Thanks!
