Comments
| Comment Type | Description |
|---|---|
| Biophysicochemical Properties | Kinetic parameters: Vmax=58.92 pmol/min/mg enzyme {ECO:0000269|PubMed:12897259}; |
| Catalytic Activity | An acyl-CoA + sn-glycerol 3-phosphate = CoA + a 2-acyl-sn-glycerol 3-phosphate. {ECO:0000269|PubMed:12897259, ECO:0000269|PubMed:20551224}. |
| Domain | The HXXXXD motif is essential for acyltransferase activity and may constitute the binding site for the phosphate moiety of the glycerol-3-phosphate. {ECO:0000250}. |
| Function | Esterifies acyl-group from acyl-ACP to the sn-2 position of glycerol-3-phosphate, a step in cutin biosynthesis. {ECO:0000269|PubMed:20551224}. |
| Similarity | Belongs to the GPAT/DAPAT family. {ECO:0000305}. |
| Subcellular Location | Membrane {ECO:0000305}; Multi-pass membrane protein {ECO:0000305}. |
| Tissue Specificity | Widely expressed at high level. Highly expressed in seedlings, developing seedlings and flower buds. {ECO:0000269|PubMed:12897259}. |
