Comparative Analysis of Root Microbiomes of Rice Cultivars with High and Low Methane Emissions Reveals Differences in Abundance of Methanogenic Archaea and Putative Upstream Fermenters. [PDF]
, 2020 Rice cultivation worldwide accounts for ∼7 to 17% of global methane emissions. Methane cycling in rice paddies is a microbial process not only involving methane producers (methanogens) and methane metabolizers (methanotrophs) but also other microbial ...

Exploring the Substrate Switch Motif of Aromatic Ammonia Lyases
ChemBioChem, Volume 24, Issue 23, December 1, 2023., 2023 Using a bioinformatic approach, we identified novel substrate switch motifs of aromatic ammonia lyases. These alternative amino acids were introduced into a tyrosine ammonia lyase (TALrpc). The characterization of these enzyme variants revealed a significant (up to 20‐fold) improvement in the activity for phenylalanine.

Diversity of ThDP-Dependent Enzymes Forming Chiral Tertiary Alcohols. [PDF]
ChembiochemChiral tertiary alcohols are widespread in nature and bioactive compounds; however, their asymmetric synthesis faces several challenges. This review outlines the toolbox of ThDP‐dependent enzymes able to produce tertiary alcohols through the formation of CC bond formation using ketones as acceptor substrates. Herein, the substrate scope, the diversity

Revival of the Names Spirochaeta litoralis, Spirochaeta zuelzerae, and Spirochaeta aurantia [PDF]
International Journal of Systematic Bacteriology, 1980 The names Spirochaeta litoralis Hespell and Canale-Parola; Spirochaeta zuelzerae (Veldkamp) Canale-Parola, Udris, and Mandel; and Spirochaeta aurantia Vinzent, which were inexplicably omitted from the Approved Lists of Bacterial Names, are revived and validly published as specified in Rules 27 and 28a and Provisional Rules B2 and B3 of the ...

Microbiome Dynamics in Early Life Stages of the Precious Mediterranean Red Coral Corallium rubrum. [PDF]
Environ Microbiol RepThe bacterial microbiota of the precious red coral Corallium rubrum matures after the first year of life. Specifically, the dominant symbionts of the adult colonies such as Spirochaetaceae were absent in larvae, settlers and recruits, suggesting that they were likely acquired horizontally from the environment between 6 months and 3 years of age ...

Molecular analysis of the distribution and phylogeny of the soxB gene among sulfur-oxidizing bacteria - evolution of the Sox sulfur-oxidizing enzyme system [PDF]
, 2007 The soxB gene encodes the SoxB component of the periplasmic thiosulfate-oxidizing Sox enzyme complex, which has been proposed to be widespread among the various phylogenetic groups of sulfur-oxidizing bacteria (SOB) that convert thiosulfate to sulfate ...

Carbohydrate Metabolism inSpirochaeta stenostrepta [PDF]
Journal of Bacteriology, 1970 The pathways of carbohydrate metabolism inSpirochaeta stenostrepta, a free-living, strictly anaerobic spirochete, were studied. The organism fermented glucose to ethyl alcohol, acetate, lactate, CO2, and H2. Assays of enzymatic activities in cell extracts, and determinations of radioactivity distribution in products formed from14C-labeled glucose ...
