Proximal Co-Translation Facilitates Detection of Weak Protein-Protein Interactions.

Ubiquitin (Ub) signals are recognized and decoded into cellular responses by Ub-receptors, proteins that tether the Ub-binding domain(s) (UBDs) with response elements. Typically, UBDs bind mono-Ub in highly dynamic and weak affinity manners, presenting challenges in identifying and characterizing their binding interfaces. Here, we report the development of a new approach to facilitate the detection of these weak interactions using split-reporter systems where two interacting proteins are proximally co-translated from a single mRNA.

Treatment indications for symptomatic versus asymptomatic florid cemento-osseous dysplasia in adult patients: a systematic review.

Objectives: The objective of this study was to identify treatment indications for symptomatic and asymptomatic florid cemento-osseous dysplasia (FCOD) in adult patients and explore relationships between clinical variables and radiographic findings (PROSPERO # CRD42023411228).

Study Design: A systematic review was conducted by independent investigators using databases: PubMed, ProQuest, Embase, Web of Science, Dentistry and Oral Sciences Database (DOSS), and TRIP to identify studies on FCOD treatment options in adults. Inclusion criteria for this systematic review included: originally in English; open-access; published between 2001 and 2021.

Engineering of methionine-auxotroph via parallel evolution of two enzymes from direct-sulfurylation pathway enables its recovery in minimal medium.

Methionine biosynthesis relies on the sequential catalysis of multiple enzymes. , the main bacteria used in research and industry for protein production and engineering, utilizes the three-step trans-sulfurylation pathway catalyzed by L-homoserine O-succinyl transferase, cystathionine gamma synthase and cystathionine beta lyase to convert L-homoserine to L-homocysteine. However, most bacteria employ the two-step direct-sulfurylation pathway involving L-homoserine O-acetyltransferases and O-acetyl homoserine sulfhydrylase.

Exploring exercise adherence and quality of life among veteran, novice, and dropout trainees.

Introduction: The purpose of this study was to identify and reveal the different contexts, variables, and factors that may influence adherence to physical activity among veteran, novice, and dropout trainees, such as the frequency of the weekly training units, the trainees preferred type of exercise, the purpose of the physical activity, and the relationship between support and supervision by fitness instructors and professionals. This study also examined the relationships between trainees, seniority and the strength of the habit and adherence to physical activity, the effects of personal variables such as age and gender on adherence to physical activity, and how the seniority and adherence of trainees may affect their quality of life.

Methods: A total of 460 participants drawn from the broader Israeli exercise community, which encompasses a diverse range of individuals within the general adult population, were engaged in this study.
