Keywords The isoflavone conjugate biochanin A-7-O-glucoside-6″-O-malonate is degraded by Fusarium javanicum with an esterase to yield biochanin A-7-O-glucoside which is further cleaved by a glucosidase to the aglycone. Biochanin A is funnelled into a known catabolic sequence (Z. Naturforsch. 37c, 861 (1982)). Induction of the catabolism of p-methoxyphenylacetic acid is linked to biochanin A degradation, whereas p-hydroxyphenylacetic acid and 3,4-dihydroxy- phenylacetic acid degradation is substrate-induced.

ABSTRACT We show here that the paaABCDE genes of the paa cluster responsible for phenylacetate degradation in Escherichia coli W encode a five-component oxygenase that hydroxylates phenylacetyl-coenzyme A (CoA), the first intermediate of the pathway. The primary structure of the subunits of bacterial phenylacetyl-CoA oxygenases revealed that these enzymes constitute the prototype of a new and distinct group of the large bacterial diiron multicomponent oxygenase family.

The complex dibutyltin 2-oxo-2-phenylacetic acid 4-hydroxybenzohydrazone has been synthesized and characterized by elemental analysis, IR, 1H and 13C NMR, and X-ray single-crystal diffraction studies. The crystal structure belongs to triclinic, space group P-1 with a=9.3220 (10) Å, b=9.8779 (11) Å, c=15.9401 (17) Å, β=97.0930 (10)∘, Z=2, V=1427.6(3) Å3, Dc=1.413 mg/cm3, μ=0.936 mm−1, F(000)=628, R=0.1158, and wR=0.2522. X-ray analysis indicates that O(2), N(2), O(4), and O(4)#1 from the ligand and O(5) from ethanol molecule are in the equatorial positions; the axial positions are occupied by two n-butyl groups. It shows a distorted pentagonal bipyramid configuration with seven-coordination for central tin atom. Fascinatingly, the supramolecular infrastructures are observed, which exist as two-dimensional sheets assembled from the organometallic subunits through intermolecular and intramolecular O–H⋯X or C–H⋯X (X = O or N) hydrogen bonds.
