The PSAT1 protein plays a central role in cellular metabolism by catalyzing the reversible conversion of 3-phosphohydroxypyruvate to phosphoserine and 3-hydroxy-2-oxo-4-phosphonooxybutyrate to phosphohydroxythreonine. These enzyme activities are key steps in the biosynthetic pathway of the essential amino acids serine and threonine. PSAT1 Protein, Human (His) is the recombinant human-derived PSAT1 protein, expressed by E. coli , with C-6*His labeled tag.
