Protein Variants

Protein Variants Comment Organism
G37D regular PCR with site-specific mutation for both DNA strands, the gene is divided into two separate amplification products, preference for NAD+ rather than NADP+, depends on an a interaction between the adenosine ribose moiety of NAD+ and the inserted aspartate side chain Levilactobacillus brevis
