Functional and evolutionary relationships among diverse oxygenases.
Oxygenases that incorporate one or two atoms of dioxygen into substrates are found in many metabolic pathways. In this article, representative oxygenases, principally those found in bacterial… Expand

Distinct effector-binding sites enable synergistic transcriptional activation by BenM, a LysR-type regulator.
BenM, a bacterial transcriptional regulator, responds synergistically to two effectors, benzoate and cis,cis-muconate. CatM, a paralog with overlapping function, responds only to muconate. Structures… Expand

Expression of the Rhodobacter sphaeroides hemA and hemT genes, encoding two 5-aminolevulinic acid synthase isozymes.
The nucleotide sequences of the Rhodobacter sphaeroides hemA and hemT genes, encoding 5-aminolevulinic acid (ALA) synthase isozymes, were determined. ALA synthase catalyzes the condensation of… Expand

benK encodes a hydrophobic permease-like protein involved in benzoate degradation by Acinetobacter sp. strain ADP1.
The chromosomal benK gene was identified within a supraoperonic gene cluster involved in benzoate degradation by Acinetobacter sp. strain ADP1, and benK was expressed in response to a benzoate… Expand

Regulation of benzoate degradation in Acinetobacter sp. strain ADP1 by BenM, a LysR-type transcriptional activator.
In Acinetobacter sp. strain ADP1, benzoate degradation requires the ben genes for converting benzoate to catechol and the cat genes for degrading catechol. Here we describe a novel transcriptional… Expand

Synergistic transcriptional activation by one regulatory protein in response to two metabolites
BenM is a LysR-type bacterial transcriptional regulator that controls aromatic compound degradation in Acinetobacter sp. ADP1. Here, in vitro transcription assays demonstrated that two metabolites of… Expand

Nucleotide sequences of the Acinetobacter calcoaceticus benABC genes for benzoate 1,2-dioxygenase reveal evolutionary relationships among multicomponent oxygenases.
The nucleotide sequences of the Acinetobacter calcoaceticus benABC genes encoding a multicomponent oxygenase for the conversion of benzoate to a nonaromatic cis-diol were determined. The enzyme,… Expand

Similarities between the antABC-encoded anthranilate dioxygenase and the benABC-encoded benzoate dioxygenase of Acinetobacter sp. strain ADP1.
Acinetobacter sp. strain ADP1 can use benzoate or anthranilate as a sole carbon source. These structurally similar compounds are independently converted to catechol, allowing further degradation to… Expand

Full-length structures of BenM and two variants reveal different oligomerization schemes for LysR-type transcriptional regulators.
BenM, a LysR-type transcriptional regulator (LTTR) from the bacterium Acinetobacter baylyi, responds synergistically to benzoate and cis,cis-muconate. With these effectors, BenM activates gene… Expand

Key Aromatic-Ring-Cleaving Enzyme, Protocatechuate 3,4-Dioxygenase, in the Ecologically Important MarineRoseobacter Lineage
ABSTRACT Aromatic compound degradation in six bacteria representing an ecologically important marine taxon of the α-proteobacteria was investigated. Initial screens suggested that isolates in… Expand
