Presence of vitamin B <sub>12</sub> metabolism in the last common ancestor of land plants

2023-06-08

Abstract excerpt

Vitamin B 12 , or cobalamin, (hereinafter B 12 ) is an essential organic micronutrient, required by humans as a cofactor for methionine synthase (METH) and for methylmalonyl CoA mutase (MCM), involved in the propionate shunt. B 12 is a complex corrinoid molecule made only by a subset of bacteria. Plants and fungi have an alternative methionine synthase (METE) that does not need a B 12 cofactor, so these organi...
