Molecular Basis for Short-Chain Thioester Hydrolysis by Acyl Hydrolases in -Acyltransferase Polyketide Synthases.
JACS Au

Department of Chemistry, University of Warwick, Coventry CV4 7AL, U.K.
Polyketide synthases (PKSs) are multidomain enzymatic assembly lines that biosynthesize a wide selection of bioactive natural products from simple building blocks. In contrast to their -acyltransferase (AT) counterparts, -AT PKSs rely on stand-alone ATs to load extender units onto acyl carrier protein (ACP) domains embedded in the core PKS machinery. -AT PKS gene clusters also encode stand-alone acyl hydrolases (AHs), which are predicted to share the overall fold of ATs but function like type II thioesterases (TEs), hydrolyzing aberrant acyl chains from ACP domains to promote biosynthetic efficiency.

College for Health, Community, and Policy, The University of Texas at San Antonio, San Antonio, TX, United States.
Objective: This study aimed to evaluate the effectiveness of combining basketball training with a traditional sensory integration therapy (SIT) vs. a SIT alone in enhancing sensory integration capability among Chinese children diagnosed with mild challenges in sensory integration and sensory processing (CSISP).
Methods: This study comprised a Control group and an Experimental group, both undergoing a 10-week intervention (4 sessions/week, 45 min/session).
P-band center modulated and heterostructure stabilized 1T-MoS as bidirectional electrocatalyst for Lithium-Sulfur batteries.

Lithium-sulfur batteries (LSBs) are considered as the most potential next-generation rechargeable energy storage devices due to their high theoretical energy density. However, the commercialization is severely hampered by the shuttle effect and sluggish sulfur redox kinetics of sulfur cathodes. Herein, we propose MoS/CN heterostructures as potential cathodes for LSBs.

Emerging contaminants (ECs) pose great challenges to water treatment technology due to their complexity and high harm. In this paper, the method of dielectric barrier discharge (DBD) plasma coupled with iron-based catalyst (FeNC) activating periodate (PI) was first designed for ECs removal. The ingenious introduction of FeNC not only promotes the Fenton-like reaction of DBD system but also reduces the PI activation energy barrier and accelerates the electron shuttle between PI and pollutants.

Microbiology Laboratory, Department of Botany (DST-FIST and UGC-DRS Funded), Institute of Science, Visva-Bharati (A Central University), Santiniketan, West Bengal, 731235, India.
To fish-out novel salt-tolerance genes, metagenomic DNA of moderately saline sediments of India's largest hypersaline Sambhar Lake was cloned in fosmid. Two functionally-picked clones helped the Escherichia coli host to tolerate 0.6 M NaCl.
