Protein
Glycerol-3-phosphate acyltransferase, chloroplastic
Gene
N/A
Organism
Cucurbita moschata (Winter crookneck squash) (Cucurbita pepo var. moschata)
Status
Reviewed - Annotation score: 3 out of 5 - Experimental evidence at protein leveli

Functioni

Esterifies acyl-group from acyl-ACP to the sn-1 position of glycerol-3-phosphate. The enzyme from chilling-resistant plants discriminates against non-fluid palmitic acid and selects oleic acid whereas the enzyme from sensitive plants accepts both fatty acids. Squash is chilling-sensitive.

Catalytic activityi

Acyl-CoA + sn-glycerol 3-phosphate = CoA + 1-acyl-sn-glycerol 3-phosphate.
