6.3.4.9	ATP + biotin + apo-[methylmalonyl-CoA:pyruvate carboxyltransferase]	covalent attachment of biotin to the epsilon amino group to specific lysines of the enzyme	Propionibacterium freudenreichii subsp. shermanii	AMP + diphosphate + [methylmalonyl-CoA:pyruvate carboxyltransferase]	-	?
6.3.4.9	ATP + biotin + apo-[methylmalonyl-CoA:pyruvate carboxyltransferase]	biotination of the apo-1.3SE subunit, MW 12000, the apo6SE, MW 144000, and the complete apotranscarboxylase, MW 1200000, occurs at approximately the same rates. Biotination occurs only on the 1.3SE subunit of the apotranscarboxylase	Propionibacterium freudenreichii subsp. shermanii	AMP + diphosphate + [methylmalonyl-CoA:pyruvate carboxyltransferase]	-	?
