Such detoxification systems are of particular importance for methylotrophic microorganisms that rely on formaldehyde as a central metabolite in their one-carbon metabolism. Understanding formaldehyde dissimilation pathways in non-methylotrophic industrial microorganisms is necessary for ongoing research aiming at engineering methylotrophy into their metabolism (synthetic methylotrophy). There is a variety of formaldehyde dissimilation pathways across microorganisms, often based on the activity of formaldehyde dehydrogenases. In this study, we investigated the role of the\n              <jats:italic>yycR<\/jats:italic>\n              gene of\n              <jats:italic>Bacillus subtilis<\/jats:italic>\n              putatively encoding a novel, uncharacterized zinc-type alcohol dehydrogenase-like protein.

Biochemical analyses demonstrated that YycR activity is optimal at 40\u00b0C, with the highest measured activity at pH 9.5, formaldehyde is the preferred substrate, and the kinetic constants are\n              <jats:italic>\n                K\n                <jats:sub>m<\/jats:sub>\n              <\/jats:italic>\n              of 0.19 \u00b1 0.05 mM and\n              <jats:italic>V<\/jats:italic>\n              <jats:sub>max<\/jats:sub>\n              of 2.24 \u00b1 0.05 nmol min\n              <jats:sup>\u22121<\/jats:sup>\n              . Altogether, we showed that YycR is a novel formaldehyde dehydrogenase with a role in formaldehyde detoxification in\n              <jats:italic>B. subtilis<\/jats:italic>\n              , providing valuable insights for future research on synthetic methylotrophy in this organism.\n            <\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>IMPORTANCE<\/jats:title>\n            <jats:p>\n              Formaldehyde is a key metabolite in methanol assimilation for many methylotrophic microorganisms, and at the same time, it is toxic to all living cells, which means its intracellular concentrations must be tightly controlled. An in-depth understanding of methanol detoxification systems in industrially relevant microorganisms is a prerequisite for the introduction of methanol utilization pathways into their metabolism (synthetic methylotrophy).\n              <jats:italic>Bacillus subtilis<\/jats:italic>\n              , an industrial workhorse conventionally used for the production of enzymes, is known to possess two formaldehyde detoxification pathways.
