Identification of the Gene Cluster for the Anaerobic Degradation of 3,5-Dihydroxybenzoate (α-Resorcylate) in Thauera aromatica Strain AR-1.
Thauera aromatica strain AR-1 degrades 3,5-dihydroxybenzoate (3,5-DHB) with nitrate as an electron acceptor. Previous biochemical studies have shown that this strain converts 3,5-DHB to hydroxyhydroquinone (1,2,4-trihydroxybenzene) through water-dependent hydroxylation of the aromatic ring and subsequent decarboxylation, and they suggest a pathway homologous to that described for the anaerobic ...
متن کاملCrystal structures of dialkylglycine decarboxylase inhibitor complexes.
The crystal structures of four inhibitor complexes of dialkylglycine decarboxylase are reported. The enzyme does not undergo a domain closure, as does aspartate aminotransferase, upon inhibitor binding. Two active-site conformations have been observed in previous structures that differ in alkali metal ion content, and two active-site conformations have been shown to coexist in solution when a s...
متن کاملProtein-protein interactions within type III secretion system-dependent pili of Rhizobium sp. strain NGR234.
Pili synthesized by the type III secretion system of Rhizobium species strain NGR234 are essential for protein secretion and thus for efficient symbiosis with many legumes. Isolation and partial purification of these pili showed that they are composed of at least three proteins, NopA, NopB, and NopX. Using biochemical assays, we show here that these proteins interact directly with one another.
متن کاملRhizobium sp. strain NGR234 NodZ protein is a fucosyltransferase.
Rhizobium sp. strain NGR234 produces a large family of lipochitooligosaccharide Nod factors carrying specific substituents. Among them are 3-O- (or 4-O-) and 6-O-carbamoyl groups, an N-methyl group, and a 2-O-methylfucose residue which may bear either 3-O-sulfate or 4-O-acetyl substitutions. Investigations on the genetic control of host specificity revealed a number of loci which directly affec...
متن کاملRhizobium soli sp. nov., isolated from soil.
A Gram-negative, non-motile, pale-yellow, rod-shaped bacterial strain, DS-42(T), was isolated from a soil in Korea and its taxonomic position was investigated by a polyphasic study. Strain DS-42(T) grew optimally at 25 degrees C and pH 7.0-8.0. Strain DS-42(T) did not form nodules on three different legumes, and the nodD and nifH genes were also not detected by PCR. Strain DS-42(T) contained Q-...
