RPSBLAST alignment for GI: 254781026 and conserved domain: TIGR02442
>gnl|CDD|162859 TIGR02442, Cob-chelat-sub, cobaltochelatase subunit. A number of genomes (actinobacteria, cyanobacteria, betaproteobacteria and pseudomonads) which apparently biosynthesize B12, encode a cobN gene but are demonstrably lacking cobS and cobT. These genomes do, however contain a homolog (modelled here) of the magnesium chelatase subunits BchI/BchD family. Aside from the cyanobacteria (which have a separate magnesium chelatase trimer), these species do not make chlorins, so do not have any use for a magnesium chelatase. Furthermore, in nearly all cases the members of this family are proximal to either CobN itself or other genes involved in cobalt transport or B12 biosynthesis. Length = 633
