Summary: This study presents a novel GH113 beta-mannanase, BaMan113A, with substrate preference towards manno-oligosaccharides. Mutagenesis successfully increased its activity and altered the product distribution towards polysaccharides. The structural features and engineering strategies for enhancing the endo-acting activity of BaMan113A were also discussed.

Summary: In this study, a acidophilic GH5 beta-mannanase with high activity and tolerance to acidic environments was efficiently expressed in Pichia pastoris. The enzyme showed specificity towards locust bean gum and exhibited optimal activity at pH 4.0 and 65 degrees C. Site-directed mutagenesis confirmed the crucial catalytic residues of the enzyme. Additionally, a synergistic effect was observed when the enzyme was combined with a commercial alpha-galactosidase.

Summary: The study demonstrated that the mutant R171K/E205D had a twofold higher propensity for transglycosylation with mannotetraose and allyl alcohol compared to wild-type TrMan5A. By employing enzyme synergy with GH27 guar alpha-galactosidase, there was a 2.1-fold increase in allyl mannosides and significant production of allyl galactopyranoside, leading to a 4.4-fold increase in overall yield of allyl glycosides.

Summary: Fennel seeds were identified as a promising source of polyphenol oxidase (PPO) and the purified PPO enzyme was characterized in detail for the first time. The enzyme showed the best activity towards the substrate catechol, suggesting potential industrial applications in producing low-cost enzymes. Inhibitors and organic solvents were found to impact PPO activity, with certain solvents maintaining the enzyme's activity at high concentrations.

Summary: This study investigated the production of low molecular weight galactomannan (LMW-GM) from leguminous seeds using enzymatic hydrolysis. The researchers used a one-pot fermentation technology to cultivate Trichoderma reesei with a cocktail of beta-mannanase and alpha-galactosidase. The results showed that a combination of avicel and melibiose as carbon sources resulted in an enzyme cocktail with high activities of beta-mannanase and alpha-galactosidase. The use of melibiose effectively induced the production of alpha-galactosidase, which improved the degradation of galactose in GM and increased the yield of LMW-GM.

Summary: The maize brassinosteroid-signaling kinase gene ZmBSK1 plays a significant role in the response to salt stress. Overexpression of ZmBSK1 improves salt tolerance in maize by reducing cellular damage and oxidative stress and modulating the expression of antioxidant defense enzymes and proline biosynthesis-related genes.

Summary: This study reports the properties of a xanthan-degrading enzyme called Mibgl3, isolated from Microbacterium sp. XT11. Mibgl3 shows typical structural features of the GH3 family, but has low sequence identity with other GH3 enzymes. It exhibits a wide pH range tolerance and can be activated by high concentrations of NaCI, making it commercially valuable. Mibgl3 has higher substrate specificity for oligoxanthan and can effectively hydrolyze it to release glucose and glucuronate. This knowledge of Mibgl3's enzymatic properties and hydrolysis mechanism will be beneficial for future applications.

Summary: The beta-mannanase present in the commercial enzyme Pectinex Ultra SP-L exhibited efficient activity in hydrolyzing copra meal to produce mannooligosaccharides (MOS). Optimum mannanase activity was observed at pH 4.0 and a temperature of 65 degrees C. The hydrolysate obtained from the hydrolysis of copra meal using Pectinex Ultra SP-L contained approximately 45% oligosaccharides, with mannobiose being the predominant component. This study presents a simple and efficient method for obtaining oligosaccharides from copra meal using a commercial pectinolytic enzyme.

Summary: This study characterized a novel subclass B2 MBL called BioF identified in an environmental Pseudomonas sp. strain, which functions as a potent carbapenemase with incipient activity against some cephalosporins. The BioF activity is not affected by excess zinc but is only inhibited at high metal chelator concentrations, highlighting the difficulty in suppressing B2 carbapenemase activity.

Summary: The transition to terrestrial plants led to a loss of microtubule minus-end-directed dynein motors and an expansion of class-XIV kinesins. OsDLK, a class-XIV kinesin from rice, plays a role in cell elongation during development and moves into the nucleus in response to cold stress. The import of OsDLK into the nucleus might be correlated with its specific DNA binding, particularly to the Opaque2 motif, which is found in the promoter region of NtAvr9/Cf9, a transcription factor involved in cold adaptation.

Summary: This study evaluated the clinical significance of deep learning-derived brain age prediction in NMOSD and RRMS. The results showed that both NMOSD and RRMS patients had a significantly higher brain age gap compared to healthy controls. The brain age gap was associated with baseline disability score, advanced brain volume loss, and disease duration. Additionally, the brain age gap predicted the worsening of disability status in both NMOSD and RRMS patients.

Summary: This study presents a targeted comminution approach for component mixtures in a wet-operated stirred media mill. The researchers developed a process for producing battery slurries with fine ground silicon particles, carbon black, and graphite particles. By analyzing the particle size distributions of the carbon black and graphite particles separately, the slurry preparation process was transferred from a complex multistage batch process to a continuous one-passage mode. The prepared slurries were further processed into silicon-rich anodes and tested in full cells, showing comparable electrochemical behavior to anodes produced using a dissolver or mill-based slurry production process.
