Unraveling the active site cover of coproheme decarboxylase from Listeria monocytogenes

The FEBS Journal, EarlyView.
During heme biosynthesis in Gram‐positive bacteria, coproheme decarboxylase (ChdC) catalyzes the conversion of four‐propionate substrate coproheme to the two propionate product heme b. Its active site is universally covered by a flexible linking loop. This study identifies an important histidine residue, which stabilizes the loop in a ChdC homolog.

The tryptophan prenyltransferase ComQ from Bacillus subtilis 168 can prenylate daptomycin at Trp1

The FEBS Journal, EarlyView.
ComQ168 from Bacillus subtilis 168 catalyzes C‐terminal tryptophan farnesylation of ComX to generate a competence‐inducing pheromone. Recombinant ComQ168 also modifies cyclic peptides, including Daptomycin, likely at the N‐terminal tryptophan. Structural modeling highlights a C‐terminal binding region, supporting substrate promiscuity and establishing ...

Drug‐Induced Sialolithiasis—A Big‐Data Retrospective Study

Oral Diseases, EarlyView.
ABSTRACT Background Sialolithiasis pathophysiology is multifactorial, with systemic medications often hypothesised as a key contributor, particularly in older adults (Drug‐Induced Sialolithiasis). However, robust evidence supporting this theory is limited.

Characterization and parameters for the effectiveness of a UV‐C device for infection control in dental clinics

Photochemistry and Photobiology, EarlyView.
Purpose‐built UV‐C device achieves over 90% disinfection of high‐touch dental clinic surfaces. Abstract Healthcare‐associated infections (HAIs) remain a significant concern in dental settings, especially in light of increasing antimicrobial resistance.

Chemical agents to control biofilm formation in step 1 of care—Toothpastes and mouthwashes/concepts and challenges

Periodontology 2000, EarlyView.
Abstract Maintaining optimal oral hygiene is important for overall oral care, ensuring the well‐being of teeth and their surrounding tissues. In addition, it promotes fresh breath and a pleasing smile. A key element of oral self‐care is the daily use of toothpaste during regular brushing.
