Identification and characterization of emNagⅡ, a novel β-1,2-N-acetylglucosaminidase from Elizabethkingia meningoseptica

This paper identifies and characterizes emNagⅡ, a β-1,2-N-acetylglucosaminidase from Elizabethkingia meningoseptica that removes β-1,2-linked N-acetylglucosamine from living cell surfaces.

Identification and characterization of a novel exo-(N-)glycanase activity of NGLY1 on ENGase-digested N-GlcNAc proteins in vitro

This study identifies and characterizes a novel exo-(N-)glycanase activity of NGLY1 on N-GlcNAc proteins in vitro, expanding its functional repertoire and linking it to clinical features of NGLY1-CDDG.

Down regulation of Engase in Caenorhabditis elegans may improve its stresses adaptivity

This study shows that downregulating CeEngase in C. elegans enhances its adaptability to heat and osmotic stress.

Bacterial fucosidase enables the production of Bombay red blood cells

This paper describes a method using bacterial fucosidase to produce H antigen-deficient red blood cells for transfusion to individuals with anti-H antibodies.
