Serine hydroxymethyltransferase (SHMT) catalyzes the interconversion of serine and glycine, which is crucial for one carbon metabolism. Here, we report the first crystal structure of cytoplasmic SHMT fromPichia pastoris(pcSHMT) diffracted to 2.5 Å resolution in space groupC2221. PcSHMT was a contaminant with our target protein expressed inPichia pastorisand confirmed by mass spectrometry. The overall structure of pcSHMT is similar toHumanmitochondrial SHMT and different toE. coliSHMT. Interestingly, the oligomerization of pcSHMT expressed in eukaryotic or prokaryotic system differs significantly and is regulated by pyridoxal-5′-phosphate. Our results revealed a close evolutionary relationship betweenPichia pastorisandHumanmitochondria.
