Protein

Type 4 prepilin-like proteins leader peptide-processing enzyme

Gene

tapD

Organism
Aeromonas salmonicida (strain A449)
Status
Reviewed-Annotation score: Annotation score: 2 out of 5-Protein inferred from homologyi

Functioni

Cleaves type-4 fimbrial leader sequence and methylates the N-terminal (generally Phe) residue. Processes the TapA pilin precursor during membrane translocation (By similarity).By similarity

Catalytic activityi

Typically cleaves a -Gly-|-Phe- bond to release an N-terminal, basic peptide of 5-8 residues from type IV prepilin, and then N-methylates the new N-terminal amino group, the methyl donor being S-adenosyl-L-methionine.

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
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.
