Revisiting D-Acylases for D-Amino Acid Production. [PDF]

Microb Biotechnol
Enzymatic D‐acylase/N‐succinyl‐amino acid racemase tandem for the production of optically pure D‐amino acids and structural basis for D‐acylase substrate recognition. ABSTRACT N‐Acyl‐D‐amino acid deacylases (EC 3.5.1.81, also known as D‐acylases) have been studied for decades for their utility in the kinetic resolution of N‐acetyl‐D,L‐amino acids (NAAs)

Protein Quakes in Redox Metalloenzymes: Clues to Molecular Enzyme Conductivity Triggered by Binding of Small Substrate Molecules. [PDF]

ChemistryOpen
Metalloenzyme conformational changes accompany electrocatalytic action. Two‐centre copper nitrite reductases (CuNIRs) are examples, mostly without non‐turnover voltammetry on Au(111)‐surfaces, while nitrite substrate triggers electrocatalysis, CuNIR conductivity, and enzyme structural expansion. We offer a quantum chemical rationale.

The structure of the complex between the arsenite oxidase from Pseudorhizobium banfieldiae sp. strain NT‐26 and its native electron acceptor cytochrome c552

Acta Crystallographica Section D, Volume 79, Issue 4, Page 345-352, April 2023., 2023
The crystal structure of the electron transfer complex between arsenite oxidase (AioAB) from Pseudorhizobium banfieldiae sp. strain NT‐26 and its native electron acceptor cytochrome c552 (cytc552) is presented. Cytc552 docks within a cleft at the interface of the AioA and AioB subunits, which allows a close association between redox cofactors.; this ...

Impact of benzalkonium chloride, benzethonium chloride and chloroxylenol on bacterial antimicrobial resistance

Journal of Applied Microbiology, Volume 133, Issue 6, Page 3322-3346, December 2022., 2022
Abstract This review examined 3655 articles on benzalkonium chloride (BKC), benzethonium chloride (BZT) and chloroxylenol (CHO) aiming to understand their impact on antimicrobial resistance. Following the application of inclusion/exclusion criteria, only 230 articles were retained for analysis; 212 concerned BKC, with only 18 for CHO and BZT.

The Mechanism of Biochemical NO‐Sensing: Insights from Computational Chemistry

Chemistry – A European Journal, Volume 28, Issue 49, September 1, 2022., 2022
The production of cGMP and the resulting regulation of numerous physiological functions is regulated by the NO signaling pathway which occurs in soluble guanylate cyclase (sGC). Previously investigated by experiment, the exact details of the mechanism remain unclear, as two active states have been proposed. In this work, using computational techniques,

Bacterial diversity significantly reduces toward the late stages among filarial lymphedema patients in the Ahanta West District of Ghana: A cross‐sectional study

Health Science Reports, Volume 5, Issue 4, July 2022., 2022
Abstract Background Lymphatic Filariasis (LF), a neglected tropical disease, has been speculated to be complicated by secondary bacteria, yet a systematic documentation of these bacterial populations is lacking. Thus, the primary focus of this study was to profile bacteria diversity in the progression of filarial lymphedema among LF individuals with or

Role of Microbes and Nanomaterials in the Removal of Pesticides from Wastewater

International Journal of Photoenergy, Volume 2022, Issue 1, 2022., 2022
Pesticides are a class of xenobiotic compounds that are recalcitrant and show persistence in the environment for a longer period of time. Research studies have linked their potential for mutagenicity, teratogenicity, and carcinogenicity. The accumulation of pesticides in water sources due to runoff from agricultural lands has posed a serious threat to ...

Achromobacter xylosoxidans (Alcaligenes xylosoxidans subsp. xylosoxidans) meningitis associated with a gunshot wound [PDF]

Journal of Clinical Microbiology, 1988
The microbiological and clinical features of a case of Achromobacter xylosoxidans (Alcaligenes xylosoxidans subsp. xylosoxidans) meningitis associated with a gunshot wound are described. To our knowledge, this is the third confirmed case report of meningitis caused by this organism.

Isolation and Characterization of Diesel‐Degrading Bacteria from Hydrocarbon‐Contaminated Sites, Flower Farms, and Soda Lakes

International Journal of Microbiology, Volume 2022, Issue 1, 2022., 2022
Hydrocarbon‐derived pollutants are becoming one of the most concerning ecological issues. Thus, there is a need to investigate and develop innovative, low‐cost, eco‐friendly, and fast techniques to reduce and/or eliminate pollutants using biological agents.

Reverse protein engineering of a novel 4‐domain copper nitrite reductase reveals functional regulation by protein–protein interaction

The FEBS Journal, Volume 288, Issue 1, Page 262-280, January 2021., 2021
We discovered a new class of 4‐domain Cu‐containing nitrite reductase (CuNiR) from Bradyrhizobium sp. ORS 375 that has both cytochrome (Cytc) and cupredoxin (Cup) domains tethered to catalytic core (Core) domain at the N‐terminus. This article reports the first characterization of this enzyme (BrNiR) and its domain‐truncated 3‐ and 2‐domain mutants ...
