Organism	Comment	Expression
Glycine max	gene cis-elements respond to biotic and abiotic stress, the enzyme is expressed under conditions of water or salinity stress, during infection with pathogens, in response to salicylic acid signaling, during somatic embryo differentiation, in immature seeds, in root tissues, and in soybean calli grown in the dark	up

General Information

General Information	Comment	Organism
metabolism	CPT is a key enzyme in the metabolism of oil in soybean seeds, the enzyme is involved in lipid biosynthesis in soybean seeds and is important for triacylglycerol biosynthesis, together with lysophosphatidylcholine acyltransferase, EC 2.3.1.23. diacylglycerol can also be converted to triacylglycerol by acylation at position 3 of the glycerol molecule in a reaction catalyzed by diacylglycerol acyltransferase, EC 2.3.1.20	Glycine max
physiological function	the enzyme produces membrane lipids by reversibly converting diacylglycerol into phosphatidylcholine, which is a substrate for polyunsaturated fatty acid biosynthesis and can replenish the pool of acyl-CoA through the action of cytoplasmic lysophosphatidylcholine acyltransferase	Glycine max
