Protein

Carnocyclin-A

Gene

cclA

Organism
Carnobacterium maltaromaticum (Carnobacterium piscicola)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Cyclopeptide antibiotic that inhibits the growth of Gram-positive bacteria, but has no effect on the growth of Gram-negative bacteria.1 Publication

pH dependencei

Stable from pH 2 to 12.1 Publication

Temperature dependencei

Displays a high degree of stability when incubated at temperatures between -80 and 75 degrees Celsius for 60 minutes. Autoclaving the peptide at 121 degrees Celsius for 15 minutes had no effect but incubation at 100 degrees Celsius for 60 minutes caused a 32-fold reduction in activity.1 Publication

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.
