CC   -!- FUNCTION: Converts cobyric acid to cobinamide by the addition of
CC       aminopropanol on the F carboxylic group. However, the true cosubstrate
CC       could be (R)-1-amino-2-propanol O-2-phosphate, leading to cobinamide
CC       phosphate. {ECO:0000255|HAMAP-Rule:MF_00024}.
CC   -!- PATHWAY: Cofactor biosynthesis; adenosylcobalamin biosynthesis.
CC       {ECO:0000255|HAMAP-Rule:MF_00024}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_00024};
CC       Multi-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00024}.
CC   -!- SIMILARITY: Belongs to the CobD/CbiB family. {ECO:0000255|HAMAP-
CC       Rule:MF_00024}.
