Protein Family Models

Members of this family are UDP-N-acetylenolpyruvoylglucosamine reductase enzymes EC:1.1.1.158. This enzyme is involved in the biosynthesis of peptidoglycan. [1]. 8805513.

This family consists of various enzymes that use FAD as a co-factor, most of the enzymes are similar to oxygen oxidoreductase. One of the enzymes Vanillyl-alcohol oxidase (VAO) has a solved structure, the alignment includes the FAD binding site, called the PP-loop, between residues 99-110 [1]. The FAD molecule is covalently bound in the known structure, however the residue that links to the FAD is not in the alignment. VAO catalyses the oxidation of a wide variety of substrates, ranging form aromatic amines to 4-alkylphenols. Other members of this family include D-lactate dehydrogenase, this enzyme catalyses the conversion of D-lactate to pyruvate using FAD as a co-factor; mitomycin radical oxidase, this enzyme oxidises the reduced form of mitomycins and is involved in mitomycin resistance. This family includes MurB an UDP-N-acetylenolpyruvoylglucosamine reductase enzyme EC:1.1.1.158. This enzyme is involved in the biosynthesis of peptidoglycan [2]. [1]. 9261083.

This HMM describes MurB, UDP-N-acetylenolpyruvoylglucosamine reductase, which is also called UDP-N-acetylmuramate dehydrogenase. It is part of the pathway for the biosynthesis of the UDP-N-acetylmuramoyl-pentapeptide that is a precursor of bacterial peptidoglycan.
