CC         ChEBI:CHEBI:58299; EC=2.3.1.50;
CC   -!- COFACTOR:
CC       Name=pyridoxal 5'-phosphate; Xref=ChEBI:CHEBI:597326;
CC         Evidence={ECO:0000250};
CC   -!- PATHWAY: Lipid metabolism; sphingolipid metabolism.
CC   -!- SUBUNIT: Heterodimer with LCB1. Component of the serine
CC       palmitoyltransferase (SPT) complex, composed of LCB1 and LCB2 (By
CC       similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Endoplasmic reticulum membrane {ECO:0000250};
CC       Single-pass membrane protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the class-II pyridoxal-phosphate-dependent
CC       aminotransferase family. {ECO:0000305}.
