Protein

Protein-glutamine gamma-glutamyltransferase

Gene

tgl

Organism
Bacillus subtilis (strain 168)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at protein leveli

Functioni

Probably plays a role in the assembly of the spore coat proteins by catalyzing epsilon-(gamma-glutamyl)lysine cross-links. In wild-type spores at 37 degrees Celsius, tgl mediates the cross-linking of GerQ in higher molecular mass forms, probably in cooperation with YabG.

Catalytic activityi

Protein glutamine + alkylamine = protein N(5)-alkylglutamine + NH3.

Pathology & Biotechi

Disruption phenotypei

In cells missing this gene some GerQ multimers are present, indicating that tgl is not essential. Heat treatment for 20 minutes at 60 degrees Celsius, which maximally activates the Tgl enzymatic activity, causes cross-linking of GerQ in isolated yabG-deleted spores but not in tgl/yabG double-mutant spores. Additionally, the germination frequency of the tgl/yabG double-mutant spores in the presence of L-alanine with or without heat activation at 60 degrees Celsius is lower than that of wild-type spores.1 Publication

100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into one UniRef entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
