Overexpression and molecular characterization of Aga50D from Saccharophagus degradans 2-40: an exo-type β-agarase producing neoagarobiose
Abstractβ-Agarases are mostly categorized into three glycoside hydrolase (GH) families 16, 50, and 86. Recent genomic analysis of Saccharophagus degradans 2–40 revealed the presence of five agaraseExpand
