Identification
NameNADPH-dependent 1-acyldihydroxyacetone phosphate reductase
Synonyms
  • ADR
  • 1-acyl DHAP reductase
  • Acyl/alkyl DHAP reductase
  • Acylglycerone-phosphate reductase
Gene NameAYR1
Enzyme Class
Biological Properties
General FunctionInvolved in oxidoreductase activity
Specific FunctionCan convert acyl and alkyl dihydroxyacetone-phosphate (DHAP) into glycerolipids and ether lipids, respectively. Required for the biosynthesis of phosphatidic acid via the DHAP pathway, where it reduces 1-acyl DHAP to lysophosphatidic acid (LPA). Required for spore germination
Cellular LocationLipid droplet. Endoplasmic reticulum
