L-allo-Threonine is a reactant used in the synthesis of an antibiotic, globomycin, and its congener, SF-1902 A5. | [Definition]
ChEBI: L-allothreonine is the L-enantiomer of allothreonine. It has a role as an Escherichia coli metabolite and a Saccharomyces cerevisiae metabolite. It is an allothreonine and a L-alpha-amino acid. It is an enantiomer of a D-allothreonine. It is a tautomer of a L-allothreonine zwitterion. |
