Protein
Cobalamin biosynthesis protein CbiB
Organism
Salmonella arizonae (strain ATCC BAA-731 / CDC346-86 / RSK2980)
Function
Converts cobyric acid to cobinamide by the addition of aminopropanol on the F carboxylic group. However, the true cosubstrate could be (R)-1-amino-2-propanol O-2-phosphate, leading to cobinamide phosphate.
Similarity
Belongs to the CobD/CbiB family.
