Characterization of a GH17 laminarinase, MlGH17A, from a laminarin polysaccharide utilization locus in the marine bacterium Muricauda lutaonensis

Leila Allahgholi, Maik G. N. Derks, Antoine Moenaert, Zehui Dong, Justyna M. Dobruchowska, Javier A. Linares‐Pastén, Ólafur H. Friðjónsson, Guðmundur Óli Hreggviðsson, Eva Nordberg Karlsson

This study identifies and characterizes a GH17 laminarinase, MlGH17A, from a PUL in Muricauda lutaonensis, showing its ability to degrade laminarin into specific oligosaccharides and revealing structural features distinct from plant GH17 enzymes.
