In Hyphomicrobium denitrificans, the use of thiosulfate as a supplemental electron donor is regulated by two homologous sulfane‐sulfur responsive ArsR‐type transcriptional repressors, sHdrR and SoxR, that act cooperatively. Remarkably, the regulation by sHdrR/SoxR extends far beyond sulfur oxidation and deeply affects anaerobic metabolism, particularly

A putative thrazarine biosynthetic gene cluster is discovered in the genome sequence of Streptomyces coerulescens MH802‐fF5. In vivo and in vitro analyses of ThzN, a hydrazine synthetase with cupin and methionyl‐tRNA synthetase‐like domains encoded in the cluster, showed that it synthesizes a key intermediate of thrazarine by catalyzing condensation ...

Characterization of C-S Lyase from C. diphtheriae [PDF]
The emergence of antibiotic resistance in microbial pathogens requires the identification of new antibacterial drugs. The biosynthesis of methionine is an attractive target because of its central importance in cellular metabolism.

Dimeric pyruvate formate‐lyase cleaves pyruvate using a radical‐based mechanism. G734 serves as a radical storage location, and the radical is transferred to the catalytic C419 residue. Mutation of the C418‐C419 pair causes loss of enzyme activity, but does not impede radical introduction onto G734. Therefore, cis‐ but not trans‐radical transfer occurs

Expanding the Biocatalytic Toolbox of C-N Lyases:Rational Engineering and Enzyme Discovery [PDF]
With the growing demand for nonhazardous and sustainable alternatives for chemical catalysis, interest in biocatalysts has grown significantly over the past decades. The enzyme ethylenediamine-N,N’-succinic acid (EDDS) lyase from Chelativorans sp.

An Enzymatic Prodrug‐like Route to Thio and Selenoamides [PDF]
6‐Thioguanine (6TG) is a clinically used antitumor agent that was rationally designed as a DNA‐targeting antimetabolite, but it also occurs naturally. 6TG is a critical virulence factor produced by Erwinia amylovorans , a notorious plant pathogen that ...

COMPARATIVE APPROACHES FOR PLANT GENOMES: UNRAVELING "INTRA" AND "INTER" SPECIES RELATIONSHIPS FROM PRELIMINARY GENE ANNOTATIONS [PDF]
Comparative genomics studies the differences and similarities between different species, to transfer biological information from model organisms to newly sequenced genomes, and to understand the evolutionary forces that drive changes in genomic features ...

Bacterial hemoglobins and flavohemoglobins: versatile proteins and their impact on microbiology and biotechnology [PDF]
In response to oxygen limitation or oxidative and nitrosative stress, bacteria express three kinds of hemoglobin proteins: truncated hemoglobins (tr Hbs), hemoglobins (Hbs) and flavohemoglobins (flavo Hbs).

Quantitative and evolutionary global analysis of enzyme reaction mechanisms [PDF]
The most widely used classification system describing enzyme-catalysed reactions is the Enzyme Commission (EC) number. Understanding enzyme function is important for both fundamental scientific and pharmaceutical reasons.

Function and redox state of mitochondrial localized cysteine-rich proteins important in the assembly of cytochrome \u3ci\u3ec\u3c/i\u3e oxidase [PDF]
The cytochrome c oxidase (CcO) complex of the mitochondrial respiratory chain exists within the mitochondrial inner membrane (IM). The biogenesis of the complex is a multi-faceted process requiring multiple assembly factors that function on both faces of
