Comments
| Comment Type | Description |
|---|---|
| Catalytic Activity | Palmitoyl-CoA + L-serine = CoA + 3-dehydro-D- sphinganine + CO(2). |
| Cofactor | Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326; Evidence={ECO:0000250}; |
| Function | Serine 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}. |
| Pathway | Lipid metabolism; sphingolipid metabolism. |
| Similarity | Belongs to the class-II pyridoxal-phosphate-dependent aminotransferase family. {ECO:0000305}. |
| Subcellular Location | Endoplasmic reticulum membrane {ECO:0000269|PubMed:1317856}; Single-pass membrane protein {ECO:0000269|PubMed:1317856}. |
| Subunit | Heterodimer 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 Specificity | Expressed in a variety of tissues. |
