This entry represents the extended beta-sheet domain (EBD, also known as DUF1975) of UDP-N-acetylglucosamine--peptide N-acetylglucosaminyltransferase GtfA subunit [1,2]. GtfA is the core enzyme of the OGT complex, which also includes the co-activator GtfB, to glycosylate the serine-rich repeat (SRR) of adhesin PsrP in Streptococcus pneumoniae, a protein involved in the infection and pathogenesis [1,2]. The function of this domain is not clear.	Domain
