Protein Variants

Protein Variants	Comment	Organism
C43S	mutation leads to disruption of a disulfide bridge. Mutant is a trimer in solution and shows similar spectroscopic properties and enzymatic activity as the wild-type using dithionite as reductant. The kcat values of C43S mutant decrease to about 20% of wild-type when reduced B0428 is used as an electron donor	Candidatus Jettenia caeni
