 1-60 1.27e-19

cobalt transporter subunit CbtB (proposed); This model represents a family of proteins which have been proposed to act as cobalt transporters acting in concert with vitamin B12 biosynthesis systems. Evidence for this assignment includes 1) prediction of a single trans-membrane segment and a C-terminal histidine-rich motif likely to be a metal-binding site, 2) positional gene linkage with known B12 biosynthesis genes, 3) upstream proximity of B12 transcriptional regulatory sites, 4) the absence of other known cobalt import systems and 5) the obligate co-localization with a protein (CbtA) predicted to have five additional trans-membrane segments.
