CC   -!- FUNCTION: Catalyzes the transfer of a single N-acetylglucosamine from
CC       UDP-GlcNAc to a serine or threonine residue in extracellular proteins
CC       resulting in their modification with a beta-linked N-acetylglucosamine
CC       (O-GlcNAc). Specifically glycosylates the Thr residue located between
CC       the fifth and sixth conserved cysteines of folded EGF-like domains.
CC       {ECO:0000250|UniProtKB:Q8BYW9}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=L-seryl-[protein] + UDP-N-acetyl-alpha-D-glucosamine = 3-O-(N-
CC         acetyl-beta-D-glucosaminyl)-L-seryl-[protein] + H(+) + UDP;
