Caution

Lacks the conserved Asp residue in position 252 essential for pectinase activity. Likewise, most of the residues involved in substrate binding are not conserved. Was originally (PubMed:15808744) thought to have palmitoyl-CoA thioesterase activity, but PubMed:19452549 were unable to detect any pectinase or palmitoyl-CoA thioesterase activity. Its enzyme activity is therefore unsure.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.
