Abstract:
A gene, phl, encoding a phenylacetyl-CoA ligase was cloned from a phage library of Penicillium chrysogenum AS-P-78. The presence of five introns in the phl gene was confirmed by reverse transcriptase-PCR. The phl gene encoded an aryl-CoA ligase closely related to Arabidopsis thaliana 4-coumaroyl-CoA ligase. The Phl protein contained most of the amino acids defining the aryl-CoA (4-coumaroyl-CoA) ligase substrate-specificity code and differed from acetyl-CoA ligase and other acyl-CoA ligases. The phl gene was not linked to the penicillin gene cluster. Amplification of phl in an autonomous repli

Rate constants have been determined for the reactions of diazodiphenylmethane (DDM) with 3- and 4-pyridineacetic acid, 3- and 4-pyridineacetic acid N-oxide and some meta- and para-substituted phenylacetic acids in twelve alcohols. The determined rate constants, together with literature data, were used for calculation of Hammett ? values in a series of alcohols. Secondary ? constants have been calculated for substituents in meta and para-position of phenylacetic acids not given in literature, and also ? constants for 3N, 3N-O, 4N and 4N-O in pyridineacetic acids, in alcohols used.

Abstract:
Aromatic compounds comprise approximately 25% of the Earth`s biomass. Accordingly, turnover of these thermostable compounds is essential to the biogeochemical carbon cycle. Specialized microbial enzymatic pathways are largely responsible for mineralization of aromatic compounds, and are extensively studied for bioremediation purposes. The phenylacetic acid degradation pathway (PAA) is of particular interest as it is utilized for degradation of a multitude of aromatic compounds, including environmental pollutants, and appears to be widely distributed among bacteria.

Abstract:
The biosynthesis of the auxin, indole-3-acetic acid (IAA), has been well studied in recent years. It is now accepted that the indole-3-pyruvate (IPyA) pathway is the main IAA biosynthetic route and is responsible for the majority of IAA produced in plants. This pathway involves the transamination of the amino acid, tryptophan (Trp), to IPyA by the TAR (TRYPTOPHAN AMINOTRANSFERASE RELATED) enzymes, followed by the oxidative decarboxylation of IPyA to IAA by the YUCCA proteins. Recently it has been suggested that the TARs and the YUCCAs are also responsible for the biosynthesis of a less well-s

The phenylacetic acid degradation pathway of Burkholderia cenocepacia is necessary for full pathogenicity of B. cenocepacia in nematode; however, the reasons of such requirements are unknown. Unlike wild type B. cenocepacia, a deletion mutant of the phenylacetyl-CoA monooxygenase complex (ΔpaaABCDE) released phenylacetic acid extracellularly in conditions that allow infection in Caenorhabditis elegans. Addition of phenylacetic acid further decreased the pathogenicity of the ΔpaaABCDE, which cannot metabolize phenylacetic acid, but did not affect the wild type, due to phenylacetic acid consumpt
