LMPD ID
LMP010418
Gene ID
Species
Arabidopsis thaliana (Arabidopsis)
Gene Name
glycerol-3-phosphate dehydrogenase [NAD(+)] 2
Gene Symbol
Synonyms
SFD1; SUPPRESSOR OF FATTY ACID DESATURASE DEFICIENCY 1; T7D17.13; T7D17_13
Alternate Names
glycerol-3-phosphate dehydrogenase [NAD(+)] 2
Chromosome
2
EC Number
1.1.1.8
Summary
Encodes a putative dihydroxyacetone phosphate (DHAP) reductase involved in glycerol-3-phosphate supply within the chloroplast for synthesis of glycerolipids. Mutants have reduced levels of hexadecatrienoic acid, which is rescued by exogenous glycerol-3-phosphate. This gene appears to be involved in the flux of fatty acids in the prokaryotic glyerolipid biosynthesis pathway.

Biophysicochemical Properties | Kinetic parameters: KM=0.33 uM for glycerone phosphate {ECO:0000269|PubMed:22645576}; Vmax=49 umol/min/mg enzyme toward glycerone phosphate {ECO:0000269|PubMed:22645576}; |
Catalytic Activity | sn-glycerol 3-phosphate + NAD(+) = glycerone phosphate + NADH. {ECO:0000269|PubMed:14729910, ECO:0000269|PubMed:15044700, ECO:0000269|PubMed:22645576}. |
Disruption Phenotype | No visible phenotype under normal growth conditions, but leaves have decreased levels of hexadecatrienoic fatty acid (16:3) and increased levels of oleic acid (18:1). {ECO:0000269|PubMed:14729910, ECO:0000269|PubMed:15044700}. |
Function | Required to supply glycerol-3-phosphate in the chloroplast for the synthesis of glycerolipids. Required for activation of systemic acquired resistance (SAR). Provision of glycerol-3-phosphate may be involved in generating lipid signals necessary for mediating defense responses and SAR. {ECO:0000269|PubMed:14729910, ECO:0000269|PubMed:15044700, ECO:0000269|PubMed:17431038, ECO:0000269|PubMed:18088304, ECO:0000269|PubMed:22645576}. |
Pathway | Membrane lipid metabolism; glycerophospholipid metabolism. |
Similarity | Belongs to the NAD-dependent glycerol-3-phosphate dehydrogenase family. {ECO:0000305}. |
Subcellular Location | Plastid, chloroplast {ECO:0000250}. |
