MmlI is a short, approx 115 residue, protein of two alpha helices and four beta strands. It is involved in the catabolism of methyl-substituted aromatics via a modified oxo-adipate pathway in bacteria. The enzyme appears to be monomeric in some species [1] and tetrameric in others [2]. The known structure shows two copies of the protein form a dimeric alpha beta barrel.	Domain
