ID 1.19.1.1 DE flavodoxin--NADP(+) reductase. AN FPR. CA NADP(+) + reduced [flavodoxin] = 2 H(+) + NADPH + oxidized [flavodoxin]. CC -!- This activity occurs in some prokaryotes and algae that possess CC flavodoxin, and provides low-potential electrons for a variety of CC reactions such as nitrogen fixation, sulfur assimilation and amino CC acid biosynthesis. CC -!- In photosynthetic organisms it is involved in the photosynthetic CC electron transport chain. CC -!- The enzyme also catalyzes EC 1.18.1.2.
