ABSTRACT Neisseria gonorrhoeae poses an urgent public health challenge due to rapidly increasing antimicrobial resistance and the absence of an effective vaccine. Targeting conserved bacterial pathways involved in essential physiological processes may provide new opportunities for vaccine antigen discovery.

The Role of Iron‐Hyponitrite Intermediates in Biology and Insights From Synthetic Model Complexes
Despite the difference in active site architecture, NO reduction by different NOR enzymes is expected to be linked by a common intermediate: hyponitrite (N2O22−). However, experimentally, very little is known about the coordination chemistry of iron with hyponitrite and the expected Fe‐hyponitrite intermediates.

An Artificial metalloenzyme was designed by a Michael addition between a MnSalen complex and a cysteine residue within NikA crystals. The heterogeneous catalyst was found capable of an enantioselective and stereospecific epoxidation of cis‐β‐methylstyrene in cristallo.

Ectonucleoside triphosphate diphosphohydrolases (NTPDases) catalyze the hydrolysis of nucleoside tri- and di-phosphates to mono-phosphates. The products are subsequently hydrolyzed by ecto-5′-nucleotidase (ecto-5′-NT) to nucleosides.

Ni2 bispincer complexes with an embedded central imido anchor are presented. The bispincer complexes leverage the high basicity of imido ligands to facilitate 1,2 addition of weak B─H and Si─H bonds, resulting in hydrido–amido complexes and resultingly a contortion of a Ni─Ni sigma bond to form an S = 1 species. The 1,2 addition is proposed to serve as

This review summarizes recent advances in electrocatalytic sulfide oxidation (SOR), focusing on catalyst design strategies, reaction system engineering, and pathways for high‐value product generation. The roles of different reduced sulfur species (S2−, HS−, H2S) under various industrial conditions are highlighted, along with approaches to enhance ...

Fluorinated and B‐Vinylated Tris(pyridyl)borate in Copper(I) Coordination Chemistry
Coordinatively flexible tris(pyridyl)borate stabilizes copper coordination complexes, including those with ethylene and carbon monoxide. Fluorinated tris(pyridyl)borate with a vinyl substituent on boron was synthesized and comprehensively characterized, expanding the diversity and functional versatility of the poly(pyridyl)borate ligand family.

(A) Mount number, (B) mount latency, (C) intromission number, and (D) intromission latency are the parameters of sexual behavior. Met = metformin. D100 = 100 Donkwa. D90G10 = 90% Donkwa + 10% Goron‐Tula. D85G15 = 85% Donkwa + 15% Goron‐Tula. D80G20 = 80% Donkwa + 20% Goron‐Tula. The mean ± standard error of the mean (SEM) expressed the results. *Values
