No labelled methionine was formed. (l)-5-MethyltetrahydrofoIate, the natural isomer, was not a substrate for the L. casei folylpoly-γ-glutamate synthetase although the unnatural (d)-isomer was slowly metabolized to the diglutamate form., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-103-2-249
