Fig. 2: Relative position of functional groups in the predicted amino acid precursors of 12 SCPAs in comparison with the previously reported substrates of VlmD.
From: Microbial production of multiple short-chain primary amines via retrobiosynthesis

Amine and carboxylic groups in the amino acid precursors predicted using retrobiosynthesis for each SCPA are presented with yellow and green circles, respectively, in a dotted black box. Reaction center carbon atoms that are subject to chemical transformations are marked with asterisks. Precursors having the same relative position of functional groups, compared with the previously reported VlmD substrates28 in dotted blue boxes, are presented with a check mark.
