The maiA protein is a key enzyme involved in catalyzing the cis-trans isomerization of the C2-C3 double bond in maleic acid, leading to the formation of fumaric acid. By facilitating this chemical transformation, maiA plays a crucial role in regulating the isomeric configuration of the C2-C3 double bond in maleic acid, ultimately converting it into fumaric acid. maiA Protein, Serratia marcescens (FLAG, His) is the recombinant maiA protein, expressed by E. coli , with N-6*His, N-Flag labeled tag.
