These include CbiA Swiss:P29946 and CbiP Swiss:Q05597 from S.typhimurium [4], and CobQ Swiss:Q52686 from R. capsulatus [3]. These amidases catalyse amidations to various side chai ...	This family consists of various cobyrinic acid a,c-diamide synthases. These include CbiA Swiss:P29946 and CbiP Swiss:Q05597 from S.typhimurium [4], and CobQ Swiss:Q52686 from R. capsulatus [3]. These amidases catalyse amidations to various side chains of hydrogenobyrinic acid or cobyrinic acid a,c-diamide in the biosynthesis of cobalamin (vitamin B12) from uroporphyrinogen III. Vitamin B12 is an important cofactor and an essential nutrient for many plants and animals and is primarily produced by bacteria [4]. The family also contains dethiobiotin synthetases as well as the plasmid partitioning proteins of the MinD/ParA family [6].	Domain
