YjhS (NanS) is required for Escherichia coli to grow on 9-O-acetylated N-acetylneuraminic acid.

9 Sep 2009 The nanATEK-yhcH, yjhATS, and yjhBC operons in Escherichia coli are coregulated by environmental N-acetylneuraminic acid, the most prevalent sialic acid in nature. Here we show that YjhS (NanS) is a probable 9-O-acetyl N-acetylneuraminic acid ... Read more...

A close look at human IgG sialylation and subclass distribution after lectin fractionation.

30 Aug 2009 Polyspecific human IgG preparations are indicated for the treatment of primary immunodeficiency disorders associated with defects in humoral immunity. In addition, intraveneous IgG (IVIG) is used to treat patients with autoimmune and systemic ... Read more...

Structural basis for ligand and substrate recognition by torovirus hemagglutinin esterases.

29 Aug 2009 Hemagglutinin esterases (HEs), closely related envelope glycoproteins in influenza C and corona- and toroviruses, mediate reversible attachment to O-acetylated sialic acids (Sias). They do so by acting both as lectins and as receptor-destroying ... Read more...
