Engineering membrane‐bound alkane monooxygenase from Marinobacter sp. for increased activity in the selective ω‐hy‐droxylation of linear and branched aliphatic esters

open access: yesProtein Science, Volume 35, Issue 4, April 2026.
Abstract The regio‐ and stereoselective hydroxylation of unactivated C(sp3)‐H bonds is an important reaction in organic synthesis. While bacterial alkane monooxygenase AlkB catalyzes the terminal hydroxylation of aliphatic esters with excellent regioselectivity, the molecular principles of substrate recognition and selectivity of this integral membrane

Prevalence, Host Range, and Comparative Genomic Analysis of Temperate Ochrobactrum Phages

open access: yesFrontiers in Microbiology, 2017
Ochrobactrum and Brucella are closely related bacteria that populate different habitats and differ in their pathogenic properties. Only little is known about mobile genetic elements in these genera which might be important for survival and virulence ...

Cryptic Lysogeny in Proteus mirabilis

open access: yesJournal of General Virology, 1973
Summary Proteus mirabilis strains 13 and 5006 on rare occasions liberate temperate phages, 13M and 5006M, which may reinfect parent strains. These prophages are not inducible but the probability of phage liberation may be increased by growth in nitrosoguanidine. P. mirabilis strain 34 liberates a phage, φ34, spontaneously. Strain 34 is doubly lysogenic

A Foundation for Advancing Studies of the Biodegradation of Polyethylene Surrogates by Environmental and Model Laboratory Microbes

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 2, April 2026.
A polyethylene surrogate sample containing paraffin, polywax and polyethylene was exposed to selected microbes identified in this study. This image shows the surface of this surrogate following a six‐week incubation with Rhodococcus jostii. ABSTRACT Polyethylene represents a particularly recalcitrant class of plastics that persist for decades in the ...

Rhizobial motility preference in root colonization of Medicago truncatula

open access: yesNew Phytologist, Volume 250, Issue 1, Page 547-562, April 2026.
Summary Tunnel‐like infection thread (IT) structures support root colonization by symbiotic nitrogen‐fixing rhizobia bacteria in most legume species. These tip‐grown structures are key to directing rhizobia from root hairs to developing nodules, where they are hosted to fix nitrogen.

Defense Systems and Prophage Detection in Streptococcus mutans Strains

open access: yesMolecular Oral Microbiology, Volume 41, Issue 2, Page 57-68, April 2026.
ABSTRACT Although the species is extensively studied, limited data are available on antiphage defense systems (APDSs) in Streptococcus mutans. The present study aimed to explore the diversity and the occurrence of APDSs and to search for prophages in the genomes of clinical isolates of S. mutans using bioinformatics tools.

UGA4 and YBR062C Regulate Oxidative Stress Tolerance Under Heavy Metal Toxicity

open access: yesThe FASEB Journal, Volume 40, Issue 6, 31 March 2026.
Under heavy metal stress, global cap‐dependent translation is compromised. However, expression of URE2, a key gene involved in cellular tolerance to heavy metal toxicity, is maintained through an internal ribosome entry site (IRES)–mediated mode of translation.

Polyurethane Cascade Depolymerization by a Combination of Thermal Pretreatment and Enzymatic Hydrolysis

open access: yesChemSusChem, Volume 19, Issue 5, 13 March 2026.
This study explored the cascade depolymerization of a polyether‐polyester polyurethane based on a combination of low‐temperature thermal treatment and enzymatic hydrolysis. Heat pretreatment changed the physicochemical properties of polyurethane, followed by cutinase‐catalyzed hydrolysis, leading to an increase in weight loss and the production of two ...

Statistical Physics of Self-Replication

open access: yes, 2012
Self-replication is a capacity common to every species of living thing, and simple physical intuition dictates that such a process must invariably be fueled by the production of entropy. Here, we undertake to make this intuition rigorous and quantitative
