The noncanonical heme oxygenase MhuD from Mycobacterium tuberculosis binds a heme substrate that adopts a dynamic equilibrium between planar and out-of-plane ruffled conformations. MhuD degrades this substrate to an uncommon mycobilin product through successive monooxygenation and dioxygenation reactions. This article establishes a causal relationship between heme substrate dynamics and MhuD-catalyzed heme degradation, leading to a refined enzymatic […]

Distinct metabolic features in the plasma of patients with silicosis and dust-exposed workers in China: a case-control study
Silicosis is a progressive pneumoconiosis characterised by interstitial fibrosis following publicity to silica mud. The function of metabolic dysregulation in the pathogenesis of silicosis has not been investigated in element. This study aimed to establish totally different metabolic features in the plasma of patients with silicosis and dust-exposed workers with out silicosis in metabolomics research. Patients […]
