Protein Variants

Protein Variants Comment Organism
R124L results obtained under pre-steady conditions show that both Arg residues participate not only in methylmalonate semialdehyde binding via stabilizing interactions between the guanidinium groups and the carboxylate but also in the formation of an efficient MSDH-NAD+-methylmalonate semialdehyde ternary complex Bacillus subtilis
R301L results obtained under pre-steady conditions show that both Arg residues participate not only in methylmalonate semialdehyde binding via stabilizing interactions between the guanidinium groups and the carboxylate but also in the formation of an efficient MSDH-NAD+-methylmalonate semialdehyde ternary complex Bacillus subtilis
