Protein network of phosphoglycerate mutase (alr3338) (red ball) and its protein partners, according to STRING (https://string-db.org). In this figure: eno is enolase that catalyzes the reversible conversion of 2-phosphoglycerate into phosphoenolpyruvate, glyA is a serine hydroxymethyltransferase, which catalyzes the reversible interconversion of serine and glycine, with tetrahydrofolate (THF) serving as the one-carbon carrier, pgk is a phosphoglycerate kinase, it is a glycolytic enzyme, gap1 is a glyceraldehyde-3-phosphate dehydrogenase 1, an enzyme of glycolysis, gap3 is glyceraldehyde-3-phosphate dehydrogenase 3, rca is a ribulose bisphosphate carboxylase/oxygenase activase, alr1004 is alanine-glyoxylate transaminase/serine-glyoxylate transaminase, all1683 is a phosphoserine aminotransferase, trpB1 is a tryptophan synthase beta chain 1 and trpB2 is a tryptophan synthase beta chain 2.
