The first step during bacillithiol (BSH) biosynthesis involves the formation of N-acetylglucosaminylmalate from UDP-N-acetylglucosamine and l-malate and is catalyzed by a GT4 class glycosyltransferase enzyme (BshA). Recombinant Staphylococcus aureus and Bacillus subtilis BshA were highly specific and active with l-malate but the former showed low activity with d-glyceric acid and the latter with d-malate. We show that BshA is inhibited by BSH and similarly that MshA (first enzyme of mycothiol biosynthesis) is inhibited by the final product MSH.
► BshA is highly specific and active with L-malate.
► S. aureus BshA has activity with D-glyceric acid; B. subtilis BshA has activity with D-malic acid.
► Feedback inhibition of BshA and MshA occurs with bacillithiol and mycothiol, respectively.
