The function of ENSG00000127838 (PNKD, PNKD metallo-beta-lactamase domain containing) is as follows. Probable thioesterase that may play a role in cellular detoxification processes; it likely acts on a yet-unknown alpha- hydroxythioester substrate (Probable). In vitro, it is able to catalyze the hydrolysis of S-D-lactoyl-glutathione to form glutathione and D- lactic acid at very low rate, though this reaction is not physiologically relevant in vivo (PubMed:21487022). .
