additional information | NAD(P)+-dependent succinic semialdehyde dehydrogenase, BsSSADH shows similar values of the catalytic efficiency (kcat/Km) in both NAD+ and NADP+ as cofactors. The affinity of enzyme BsSSADH to NAD+ is approximately 2fold higher than that to NADP+, but the values of kcat are almost 2fold higher in the presence of NADP+ than NAD+ | Bacillus subtilis | |
