their utility in drug development, for facilitating nuclearmagneticresonance (NMR) analysis, and as probes for enzyme mechanism. Small molecule-based methods for the site-selective synthesis of deuterated amino acids typically involve de novo synthesis of the compound from deuterated precursors. In comparison, enzymatic methods for introducing deuterium offer improved efficiency, operating directly on

A PLP-dependent Mannich cyclase LolT is repurposed for α-deuteration of amino acids. Complete deuteration can be achieved with diverse L-amino acids bearing assorted functional groups, e. g. from lysine to glutamic acid. The broad substratescope and strict stereoselectivity make LolT a powerful biocatalyst for preparation of α-deuterated L-amino acids.
