AA13 polysaccharide monooxygenases (AA13 PMOs) are novel enzymes that break down starch using a copper active site in a substrate binding groove on a solvent-exposed surface. The structure of the copper active site is influenced by the residues in the groove. while the crystal structure of Cu(II)-AA13 was damaged by photoreduction and lacked two exogenous ligands. We utilized density ... https://www.diegojavierfares.com/mega-pick-SA439-EF75-5-x-7-Embroidery-Machine-Hoop-mega-pick/
