[[http://www.uniprot.org/uniprot/PLSB_CUCMO PLSB_CUCMO]] 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.

[https://www.uniprot.org/uniprot/GPAT2_CUCMO GPAT2_CUCMO] Esterifies the acyl-group from acyl-acyl carrier proteins (acyl-ACPs) to the sn-1 position of glycerol-3-phosphate (Ref.3). The physiological acyl donors in chloroplasts are acyl-ACPs, but acyl-CoAs are used as artificial donor for in vitro reactions (Probable). 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 (Ref.3). Squash is chilling-sensitive (Probable). Does not seem to discriminate between the acyl-ACP thioesters 18:1-ACP, 18:0-ACP and 16:0-ACP (Ref.3). Exhibits higher selectivity for 16:0-CoA than 18:1-CoA in vitro (PubMed:9016814, PubMed:14684887).<ref>PMID:14684887</ref> <ref>PMID:9016814</ref> <ref>PMID:9016814</ref> <ref>PMID:9016814</ref>
