Comments
Comment typeDescription
Catalytic ActivityPalmitoyl-CoA + L-serine = CoA + 3-dehydro-D- sphinganine + CO(2).
CofactorName=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326; Evidence={ECO:0000250};
FunctionSerine palmitoyltransferase (SPT). The heterodimer formed with LCB1/SPTLC1 constitutes the catalytic core. The composition of the serine palmitoyltransferase (SPT) complex determines the substrate preference. The SPTLC1-SPTLC2-SPTSSA complex shows a strong preference for C16-CoA substrate, while the SPTLC1-SPTLC2-SPTSSB complex displays a preference for C18-CoA substrate (By similarity). {ECO:0000250}.
PathwayLipid metabolism; sphingolipid metabolism.
SimilarityBelongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. {ECO:0000305}.
Subcellular LocationEndoplasmic reticulum membrane {ECO:0000269|PubMed:1317856}; Single-pass membrane protein {ECO:0000269|PubMed:1317856}.
SubunitHeterodimer with SPTLC1. Component of the serine palmitoyltransferase (SPT) complex, composed of LCB1/SPTLC1, LCB2 (SPTLC2 or SPTLC3) and ssPT (SPTSSA or SPTSSB) (By similarity). {ECO:0000250}.
Tissue SpecificityExpressed in a variety of tissues.
