ID 1.5.1.55 DE carboxyaminopropylagmatine dehydrogenase. CA N(1)-[(S)-3-amino-3-carboxypropyl]agmatine + NADP(+) + H2O = L-aspartate CA 4-semialdehyde + agmatine + NADPH + H(+). CC -!- The enzyme, characterized from the cyanobacterium Synechocystis sp. CC PCC 6803, catalyzes the reductive condensation of agmatine and CC L-aspartate 4-semialdehyde. CC -!- It participates in a biosynthetic pathway for spermidine. DR Q55131, CAPDH_SYNY3; //
