title: [Cobalamin-protein compounds of bacterial origin (a review)].
abstract: Main types of cobalamin-protein compounds from microorganisms are discussed. The first chapter of the review describes low-molecular weight cobalamin-protein complexes and their functional role in the bacterial cells. In the following chapters some structural peculiarities of B12-dependent enzymes and the nature of cobalamin-protein bounds are discussed. Possible ways for the practical use of cobalamin-protein compounds of microorganisms are under consideration.
