Curated comments from UniProt

Type	Comment	Proteins
SERB1_ARATH	function	Involved in the plastidial phosphorylated pathway of serine biosynthesis (PPSB). Catalyzes the reversible conversion of 3-phosphohydroxypyruvate to phosphoserine.
SERB1_ARATH	pathway	Amino-acid biosynthesis; L-serine biosynthesis; L-serine from 3-phospho-D-glycerate: step 2/3.
SERB1_ARATH	pathway	Cofactor biosynthesis; pyridoxine 5'-phosphate biosynthesis; pyridoxine 5'-phosphate from D-erythrose 4-phosphate: step 3/5.
SERB1_ARATH	similarity	Belongs to the class-V pyridoxal-phosphate-dependent aminotransferase family. SerC subfamily.
SERB1_ARATH	tissue specificity	Ubiquitous, but expressed preferentially in light-grown roots and shoots. Detected in root meristems and in root tissues surrounding the vascular bundle.
