Abstract
Transcobalamins, vitamin B-12 binding proteins, deliver Bit to cell su rface receptors which then permit B-12 to cross cell membranes for met abolic use. There is little documentation concerning B-12 binding prot eins in bacteria and protists. We found that prokaryotes and eukaryote s requiring B-12, as well as those protists synthesizing B-12, also pr oduce several transcobalamins for functionally transporting B-12 Simil ar to humans.
