1.3.1.33 ATP the enzyme uses ATP to drive the production of chlorophyllide a 687767 1.3.1.33 light light-activated enzyme, activation is possible at cryogenic temperatures 711484 1.3.1.33 additional information phosphatidylglycerol and sulfoquinovosyl diacylglycerol increase the affinity towards NADPH a 100fold 740022 1.3.1.33 phosphatidylglycerol active complexes of PORB preferentially bind to the lipid membranes due to the interaction with phosphatidylglycerol 762710 1.3.1.33 phosphatidylglycerol isoform PORC can bind chlorophyllide without the lipids under low NADPH concentrations. When the lipid concentration is high, PORC can oligomerize on the lipid membrane, which increases its activity 762710 1.3.1.33 phosphatidylglycerol the interaction with PG increases the affinity of the PORA towards NADPH, so active PORA complexes preferentially bind to the lipid membranes 762710 1.3.1.33 protochlorophyllide stringent requirement 393840
