Novel benzene ring biosynthesis from C(3) and C(4) primary metabolites by two enzymes.

The shikimate pathway, including seven enzymatic steps for production of chorismate via shikimate from phosphoenolpyruvate and erythrose-4-phosphate, is common in various organisms for the biosynthesis of not only aromatic amino acids but also most biogenic benzene derivatives. 3-Amino-4-hydroxybenzoic acid (3,4-AHBA) is a benzene derivative serving as a precursor for several secondary metabolites produced by Streptomyces, including grixazone produced by Streptomyces griseus. Our study on the biosynthesis pathway of grixazone led to identification of the biosynthesis pathway of 3,4-AHBA from two primary metabolites. Two genes, griI and griH, within the grixazone biosynthesis gene cluster were found to be responsible for the biosynthesis of 3,4-AHBA; the two genes conferred the in vivo production of 3,4-AHBA even on Escherichia coli. In vitro analysis showed that GriI catalyzed aldol condensation between two primary metabolites, l-aspartate-4-semialdehyde and dihydroxyacetone phosphate, to form a 7-carbon product, 2-amino-4,5-dihydroxy-6-one-heptanoic acid-7-phosphate, which was subsequently converted to 3,4-AHBA by GriH. The latter reaction required Mn(2+) ion but not any cofactors involved in reduction or oxidation. This pathway is independent of the shikimate pathway, representing a novel, simple enzyme system responsible for the synthesis of a benzene ring from the C(3) and C(4) primary metabolites. << Less

Phenoxazinone synthase: what's in a name?
Le Roes-Hill M., Goodwin C., Burton S.
The name phenoxazinone synthase (PHS, 2-aminophenol:oxygen oxidoreductase, EC 1.10.3.4) is used for the enzyme catalysing the oxidative coupling of substituted o-aminophenols to produce phenoxazinones. This review reveals that the traditional classification of PHS conflicts with recent sequence-ba ... >> More
The name phenoxazinone synthase (PHS, 2-aminophenol:oxygen oxidoreductase, EC 1.10.3.4) is used for the enzyme catalysing the oxidative coupling of substituted o-aminophenols to produce phenoxazinones. This review reveals that the traditional classification of PHS conflicts with recent sequence-based information that shows its relationship with two distinct copper protein groups. Different PHS roles, namely spore pigmentation in Streptomyces antibioticus (phsA) and biosynthesis of the antibiotic grixazone in Streptomyces griseus subsp. griseus (GriF), indicate an example of convergent evolution. Here, we review the classification, distribution and roles of PHSs, comparing them with copper oxidases at genetic and structural levels and exploring their potential application in the production of new antibiotics. << Less
