<p dir="ltr"
style="line-height:1.38;margin-top:0pt;margin-bottom:0pt;"><span style="font-size:11pt;font-family:Arial;color:#000000;background-color:transparent;font-weight:400;font-style:normal;font-variant:normal;text-decoration:none;vertical-align:baseline;white-space:pre;white-space:pre-wrap;">Molecular adaptations of microbial surfaces may aid in nutrient acquisition in oligotrophic environments. Nutrient-cell interactions that are thermodynamically favored over interactions with non-nutrient solutes could be extremely advantageous when essential nutrients are limited. The ammonia-oxidizing archaeon (AOA) Nitrosopumilus maritimus strain SCM1 (N. maritimus), a representative of the Thaumarchaeota archaeal phylum, can sustain high specific rates of ammonia-oxidation at ammonia concentrations too low to sustain metabolism by ammonia-oxidizing bacteria (AOB). AOA and AOB oxidize ammonia to hydroxylamine using homologs of the metalloenzyme ammonia monooxygenase, which requires Cu(II) as an essential cofactor for its catalytic function. One structural and biochemical difference between N. maritimus and AOB is the cell surface. A proteinaceous surface layer (S-layer) comprises the outermost boundary of the N. maritimus cell envelope, as opposed to the lipopolysaccharide coat of Gram-negative AOB. In this work, we characterized the surface affinity of N. maritimus and representative AOB with Cu(II) using surface complexation modeling and isothermal titration calorimetry. Aqueous speciation calculations with thermodynamic parameters derived from the models suggest that the cell surface of N. maritimus confers a distinct advantage in acquiring Cu(II) over AOB.</span></p>
