Gene

Protein
Glucosyltransferase 3
Organism
Streptococcus pneumoniae serotype 4 (strain ATCC BAA-334 / TIGR4)
Length
336 amino acids
Function
Required for polymorphic O-glycosylation of the serine-rich repeat protein PsrP. Catalyzes the second step in glycosylation of the serine-rich repeat protein in this bacteria. Transfers glucose from UDP-glucose to the terminal GlcNAc moiety of 3-O-(N-acetyl-alpha-D-glucosaminyl)-L-seryl-[protein] which results from the first glycosylation step of PsrP (using the short substrate SRR1-GlcNAc) (PubMed:28246170, PubMed:25404702, PubMed:21653318). Has weak hydrolytic activity against UDP-glucose and even weaker activity on UDP-galactose (PubMed:28246170). Does not complement deletion of the gtf3 gene from S.parasanguinis strain FW213 (PubMed:21653318).
Similarity
Belongs to the Gtf3 glucosyltransferase family.
