Tuberculosis
Data from University of Manchester advance knowledge in tuberculosis
August 5th, 2008
According to a study from Manchester, the United Kingdom, "Mtb (Mycobacterium tuberculosis) FprA (flavoprotein reductase A) is an NAD(P)H-dependent FAD-binding reductase that is structurally related to mammalian adrenodoxin reductase, and which supports the catalytic function of Mtb cytochrome P450s. Trp(359), proximal to the FAD, was investigated in light of its potential role in controlling coenzyme interactions, as observed for similarly located aromatic residues in diflavin reductases." "Phylogenetic analysis indicated that a tryptophan residue corresponding to Trp(359) is conserved across FprA-type enzymes and in adrenodoxin reductases. W359A/H mutants of Mtb FprA...
