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+

Single colonies are picked and the DNA is isolated and screened for the desired mutation either by restriction analysis (C103A and C249A) or by sequencing (C140A and C220A). The overall fidelity of the PCR amplification and the presence of the desired mutations are confirmed by sequencing. The plasmids containing the mutated genes are then transformed into Escherichia coli strain BL21(DE3)pLysS for protein expression.

C311A
-
mutant is still soluble but unable to catalyze succinate semialdehyde oxidation. Mutation leads to an inactive product binding both succinate semialdehyde aldehyde and gem-diol
C102A
-
mutant exhibits BADH activity between 50 and 75% that of the wild type enzyme
C103A
-
enzyme is inactive
C140A
-
activity between 50 and 75% in comparison to wild-type; mutant exhibits BADH activity between 50 and 75% that of the wild type enzyme
C220A
-
activity between 50 and 75% in comparison to wild-type; mutant exhibits BADH activity between 50 and 75% that of the wild type enzyme
C249A
-
activity between 50 and 75% in comparison to wild-type; inactive
D426A
-
strong decrease in activity
-
F138A
-
decrease in activity
-
K160A
-
Lys160 contributes to the enzyme preference to NAD+, strong decrease in activity
-
N193A
-
strong decrease in activity
-
S425A
-
decrease in activity
-
