>TIGR02442 Cob-chelat-sub cobaltochelatase subunit; InterPro: IPR012804 Cobalamin (vitamin B12) can be complexed with metal via ATP-dependent reactions (aerobic pathway) (e.g., in Pseudomonas denitrificans) or via ATP-independent reactions (anaerobic pathway) (e.g., in Salmonella typhimurium) , . The corresponding cobalt chelatases are not homologous. Cobaltochelatase is responsible for the insertion of cobalt into the corrin ring of coenzyme B12 during its biosynthesis. Two versions have been well described. CbiK/CbiX is a monomeric, anaerobic version which acts early in the biosynthesis (IPR010388 from INTERPRO). CobNST is a trimeric, ATP-dependent, aerobic version which acts late in the biosynthesis, (IPR011953 from INTERPRO, IPR006537 from INTERPRO, IPR006538 from INTERPRO) . The two pathways differ in the point of cobalt insertion during corrin ring formation . There are apparently a number of variations on these two pathways, where the major differences seem to be concerned with the process of ring contraction . Cobaltochelatase shows similarities with magnesium chelatase, which is also a complex ATP-dependent enzyme made up of two separable components. However, unlike the situation in cobaltochelatase, one of these two components is membrane bound in magnesium chelatase . .
