Recent advances in noncanonical inhibition mechanisms of anti‐CRISPR proteins

open access: yesmLife, Volume 5, Issue 2, Page 133-147, April 2026.
Abstract The CRISPR‐Cas system constitutes an adaptive immune mechanism in prokaryotes that defends against mobile genetic elements. Within the perpetual co‐evolutionary arms race between bacteria and their viral predators, bacteriophages encode anti‐CRISPR (Acr) proteins that use sophisticated molecular strategies to sabotage CRISPR‐Cas function ...

Physiologically Based Pharmacokinetic Virtual Twin Approach for Fludarabine Dosing in Pediatric Hematopoietic Stem Cell Transplantation

open access: yesCPT: Pharmacometrics &Systems Pharmacology, Volume 15, Issue 3, March 2026.
ABSTRACT Fludarabine (Flu), administered as a prodrug Flu monophosphate, is a lymphodepleting agent used prior to hematopoietic stem cell transplantation (HSCT) which exhibits substantial pharmacokinetics (PK) variability, contributing to suboptimal outcomes.

Optimized Bioconversion of Naringenin to Hesperetin in Escherichia coli With Halide Methyltransferase‐Mediated S‐Adenosylmethionine Regeneration

open access: yesEngineering in Life Sciences, Volume 26, Issue 2, February 2026.
ABSTRACT Hesperetin is a bioactive flavonoid with potential applications in pharmaceuticals and nutraceuticals, yet its low natural abundance limits commercial use. In this study, a two‐step whole‐cell bioconversion process was developed for the microbial production of hesperetin from naringenin in Escherichia coli.

Sex‐specific ethylene responses drive floral sexual plasticity in Cannabis sativa

open access: yesThe Plant Journal, Volume 125, Issue 3, February 2026.
SUMMARY Cannabis sativa L. exhibits pronounced sexual plasticity in which both XX and XY plants can undergo floral phenotypic sex reversal in response to ethylene modulation, yet the underlying molecular mechanisms remain poorly defined. Here, we present the most extensive multi‐omic analysis of ethylene‐induced sex change in C.

Recycling Nicotinamide. The Transition-State Structure of Human Nicotinamide Phosphoribosyltransferase

open access: yes, 2016
Human nicotinamide phosphoribosyltransferase (NAMPT) replenishes the NAD pool and controls the activities of sirtuins, mono- and poly-(ADP-ribose) polymerases, and NAD nucleosidase.

Characterisation of the N‐Methyltransferase SgPsmC: Application in the Kinetic Resolution of Pyrroloindolines

open access: yesAngewandte Chemie International Edition, Volume 65, Issue 2, 9 January 2026.
The N‐methyltransferase SgPsmC was characterised and applied in the kinetic resolution (KR) of easily obtainable pyrroloindolines. Substitution at 3a‐position proved to be a principal determinant for the enzyme's enantioselectivity. While moving toward laboratory scale, the reaction was coupled with a methionine adenosyl transferase for in situ ...

A Comprehensive Review of Probiotics in Alleviating Hyperuricemia: Mechanisms, Strain Engineering, and Food Applications

open access: yesFood Bioengineering, Volume 4, Issue 4, Page 546-563, December 2025.
Screening and modification of probiotics that can efficiently reduce uric acid provide a new strategy for food‐grade hyperuricemia intervention. ABSTRACT Hyperuricemia has become one of the most prevalent global epidemics, significantly impacting both the economy and the health of individuals.

Photocaged Dinucleoside Tetraphosphates for Light‐Mediated Activation of 5′ Cap Interactions and Translation In Vitro

open access: yesChemistryEurope, Volume 3, Issue 6, November 11, 2025.
Photocaged dinucleoside tetraphosphates can be incorporated into mRNA by T7 RNA polymerase. Subsequent irradiation with light activates 5′ cap interactions and translation. These 5′ cap analogs are useful tools to probe the functions of naturally occurring dinucleoside tetraphosphates and their role in bacteria and mammalian cells.

Aberrant Mitochondrial Metabolism in Alzheimer's Disease Links Energy Stress with Ferroptosis

open access: yesAdvanced Science, Volume 12, Issue 37, October 6, 2025.
Alves et al. reveal how energy loss and oxidative stress, two major features of Alzheimer's disease, are connected. Mitochondria controls the flux of the antioxidant glutathione (GSH), via facilitating both its production and consumption. Energy restriction limits GSH synthesis, conferring vulnerability to cell death by ferroptosis, implicated as a ...

The influence of adrenalectomy on monoamine oxidase and NADH cytochrome c reductase in the rat heart

open access: yes, 1977
The effect of adrenalectomy on the activities of monoamine oxidase (MAO), NADH cytochrome c reductase (NCR), succinate dehydrogenase, malate dehydrogenase, fumarase, NAD+ nucleosidase and acid phosphatase in homogenates of rat hearts was examined ...
