This entry includes the second of the two ACT domains found N-terminal of phosphoserine phosphatase (PSP, SerB). PSPs belong to the L-2-haloacid dehalogenase-like protein superfamily. PSP is involved in serine metabolism; serine is synthesized from phosphoglycerate through sequential reactions catalyzed by 3-phosphoglycerate dehydrogenase (SerA), 3-phosphoserine aminotransferase (SerC), and SerB.
