Aspergillus niger Monoamine Oxidase (MAO-N) {is a|is really a|is actually a|can be a|is often a|is usually a} homodimeric enzyme {responsible for|accountable for} the oxidation of amines {into the|in to the} corresponding imine. Laboratory evolved variants of MAO-N in {combination|mixture} {with a|having a|using a} non-selective chemical reductant represents a {powerful|potent|effective|strong|highly effective} {strategy|technique|method|approach|tactic} for the deracemisation of chiral amine mixtures and, {thus|therefore|hence|as a result}, is of interest for {obtaining|acquiring|getting} chiral amine {building|developing|creating|constructing} blocks. MAO-N presents a {rich|wealthy} conformational dynamics {with a|having a|using a} {flexible|versatile} ß-hairpin {region|area} {that can|that may|that will|that could|which will|which can} adopt closed, partially closed and open states. {Despite|Regardless of|In spite of} the ß-hairpin conformational dynamics is altered along the laboratory evolutionary pathway of MAO-N, the connection {between|in between|among|amongst|involving} the ß-hairpin conformational dynamics and active {site|website|web site|internet site|web-site|web page} catalysis {still|nonetheless|nevertheless} remains unclear. {In this|Within this} {work|function|perform|operate}, we use accelerated molecular dynamics to elucidate the {potential|possible|prospective} interplay {between|in between|among|amongst|involving} the ß-hairpin conformational dynamics and catalytic activity in MAO-N wild {type|kind|sort|variety|form} and its evolved D5 variant. Our study reveals a delicate communication {between|in between|among|amongst|involving} {both|each} MAO-N subunits that impacts the active {site|website|web site|internet site|web-site|web page} architecture, and {thus|therefore|hence|as a result} its catalytic efficiency.
