Antibacterial Siderophores of Pandoraea Pathogens and Their Impact on the Diseased Lung Microbiota
Angewandte Chemie, EarlyView.Genome mining of environmental and pathogenic Pandoraea species identified a conserved NRPS gene cluster and led to the discovery of novel siderophores, pandorabactins, which exert their antibacterial activity by depleting iron from competitors. Bioinformatic analysis of sputum from cystic fibrosis patients coupled with bioassays indicates that ...

Substrate Range and Genetic Analysis of Acinetobacter Vanillate Demethylase [PDF]
, 2000 An Acinetobacter sp. genetic screen was used to probe structure-function relationships in vanillate demethylase, a two-component monooxygenase. Mutants with null, leaky, and heat-sensitive phenotypes were isolated.

Protein import into chloroplasts: new aspects of a well-known topic [PDF]
, 2007 Protein import into plant chloroplasts is a fascinating topic that is being investigated by many research groups. Since the majority of chloroplast proteins are synthesised as precursor proteins in the cytosol, they have to be posttranslationally ...

The Regulation of Trace Metal Elements in Cancer Ferroptosis
Advanced Biology, EarlyView.The induction of ferroptosis inhibits tumor growth, enhances anticancer efficacy, and overcomes drug resistance. Recent evidence shows nonferrous metal elements play a role in ferroptosis. This review focuses on how trace metals regulate ferroptosis processes like iron accumulation, lipid peroxidation, and antioxidant defense.

Characterization and Expression Analysis of Heme Oxygenase Genes from
Bioinformatics and Biology Insights, 2019 Heme oxygenases (HOs) have a major role in phytochrome chromophore biosynthesis, and chromophores in turn have anti-oxidant properties. Plant heme oxygenases are divided into the HO1 sub-family comprising HO1, HO3, and HO4, and the HO2 sub-family, which ...

Controlled depolymerization of cellulose by light-driven lytic polysaccharide oxygenases
Nature Communications, 2020 Lytic polysaccharide (mono)oxygenases (LPMOs) perform oxidative cleavage of polysaccharides. Here, the authors showed that the light-driven activity of LPMOs is dependent on hydrogen peroxide availability and can be controlled via the light intensity ...
