Abstract
This review analyzes current information about the anaerobic type of respiration using a synthetic methacrylate compound as an electron acceptor. Both the methacrylate redox systems themselves and the anaerobic bacteria in whose cells they are found are considered. These complexes consist of flavin-containing reductase and multiheme cytochrome c3 variants. The genes of the components of the methacrylate redox systems of different microorganisms are homologous and are organized into one operon. Methacrylate-reducing activity is determined in the periplasm. The only known bacterial acrylate reductase that reduces the natural compound differs from methacrylate redox systems. The physiological role, origin, and research perspectives for this unique enzyme system are discussed.
期刊介绍：
Applied Biochemistry and Microbiology is an international peer reviewed journal that publishes original articles on biochemistry and microbiology that have or may have practical applications. The studies include: enzymes and mechanisms of enzymatic reactions, biosynthesis of low and high molecular physiologically active compounds; the studies of their structure and properties; biogenesis and pathways of their regulation; metabolism of producers of biologically active compounds, biocatalysis in organic synthesis, applied genetics of microorganisms, applied enzymology; protein and metabolic engineering, biochemical bases of phytoimmunity, applied aspects of biochemical and immunochemical analysis; biodegradation of xenobiotics; biosensors; biomedical research (without clinical studies). Along with experimental works, the journal publishes descriptions of novel research techniques and reviews on selected topics.
