Ma's Lab found O-GlcNAc on over 120 Tyr residues on proteins by an integrated ultradeep O-GlcNAc proteomics workflow. OGT and OGA can do Tyr in vitro. 👍
Wow, how could we have missed that >40 years after the discovery of O-GlcNAc? 😅

All sialoglycopeptides (sGP) in human sera carry Neu5Ac without any O-acetylation; 90% of sGP in rat sera carry Neu5Ac, with > 60% further O-acetylated. 99% of sGP in mouse sera carry Neu5Gc including 12% O-acetylated.
