General Information

EC Number General Information Comment Organism
3.1.3.27 physiological function mutant plants lacking phosphatidylglycerophosphate phosphatase activity contain reduced amounts of chlorophyll, but photosynthetic quantum yield remains unchanged. The absolute content of plastidial phosphatidylglycerol (34:4; total number of acyl carbons:number of double bonds) is reduced by about 1/3. Expression of Pgpp1 gene complements the defect of a yeast Gep4 mutant Arabidopsis thaliana
