. "This is a large and diverse family of putative metal chaperonesthat can be separated into up to 15 subgroups. In addition to known roles in cobalamin biosynthesis [1] and the activation of the Fe-type nitrile hydratase, this family is also known to be involved in the response to zinc limitation. The CobW subgroup involved in cobalamin synthesis represents only a small sub-fraction of the family [2]. " . "CobW_C" . "Cobalamin synthesis protein cobW C-terminal domain" . "Bateman A" .
