Ketol-acid reductoisomerase (KARI; EC:1.1.1.86), also known as acetohydroxy acid isomeroreductase (AHIR or AHAIR), catalyses the conversion of acetohydroxy acids into dihydroxy valerates in the second step of the biosynthetic pathway for the essential branched-chain amino acids valine, leucine, and isoleucine [1, 2, 3, 4, 5, 6]. KARI is present only in bacteria, fungi, and plants, but not in animals. KARIs are divided into two classes on the basis of sequence length and oligomerisation state. Class I KARIs are ~340 amino acid residues in length and include all fungal KARIs, whereas class II KARIs are ~490 residues long and include all plant KARIs. Bacterial KARIs can be either class I or class II. KARIs are composed of two types of domains, an N-terminal Rossmann fold domain and one or two C-terminal knotted domains. Two intertwinned knotted domains are required for function, and in the short-chain or class I KARIs, each polypeptide chain has one knotted domain. As a result, dimerization of two monomers forms two complete KARI active sites. In the long-chain or class II KARIs, a duplication of the knotted domain has occurred and, as a result, the protein does not require dimerisation to complete its active site [1, 2, 3, 4, 5, 6]. The alpha-helical KARI C-terminal knotted domain can be described as a six-helix core in which helices coil like cable threads around each other, thus forming a bundle [1, 2, 3, 4, 5].	Domain
