Microbial metalloenzyme

Microbial metalloenzymes are a broad class of enzymes found in bacteria (especially gut microbes) that require metal ions such as iron, zinc, copper, manganese, molybdenum, cobalt, or nickel as essential cofactors for catalytic activity[1][2][7][8]. These enzymes perform diverse and critical biochemical functions, including redox transformations, detoxification, degradation of dietary and host-derived small molecules, and maintenance of microbial metabolism in oxygen-limited environments[1][2][7]. They enable microbes to use alternative nutrients and modulate the bioactivity of compounds relevant to host health (including neurotransmitters and xenobiotics)[9]. Microbial metalloenzymes are prevalent in human-associated microbiota and have significant implications for drug metabolism, pathogenesis, and disease modulation[1][2][9]. Because they play central roles in microbial survival and interaction with the host, they are emerging as important targets for therapeutic intervention, including in the development of antimicrobial agents that inhibit metalloenzyme activity[5][6]. However, "microbial metalloenzymes" is a collective and non-specific term covering a large and heterogeneous group of enzyme families, rather than a single molecular target, which should be noted when considering drug targeting or biomarker discovery[1][2][5]. Key notes for structuring information: - The term "microbial metalloenzyme" does not refer to a single molecular entity but a group/family of targets; specific examples (such as molybdenum-dependent catechol dehydroxylase, superoxide dismutases, metallo-β-lactamases, etc.) can be referenced for more granular data[1][3][9]. - Appropriate canonical names should be used when focusing on individual enzymes within the broader class. - The field is of high biomedical relevance, especially for antibiotic development and modulation of the gut microbiome[1][2][5]. Is_incorrect rationale: The provided target is not a single gene/protein but an entire class, so the entry lacks the specificity required of most molecular targets. It is too broad to map to an individual canonical form[1][2][5].
