PROCESS FOR PRODUCING AND USING POLYPEPTIDES PARTICIPATING IN THE BIOSYNTHESIS OF COBALAMINS AND/OR COBAMIDES AND DNA SEQUENCES ENCODING THEM

摘要

Novel polypeptides involved in the biosynthesis of cobalamines and/or cobamides, in particular coenzyme B12, genetic material responsible for expressing these polypeptides, and a method for preparing them, are described. A method for amplifying the production of cobalamines, and particularly coenzyme B12, using recombinant DNA techniques, are also described.
