Abstract

It was shown that L-arginine (up to 0.5 mM) competitively inhibits the NADPH-diaphorase activity in drosophila melanogaster. The value of inhibition constant is equal to 103 microM. In the presence of higher concentration of L-arginine total NADPH-diaphorase activity includes not only the L-arginine inhibited component, but also the non-inhibited one.
