Miscellaneous

In each ORF of eryA two modules are present each coding for a functional synthase subunit. Thus eryA showing 3 ORFs codes for 6 synthase subunits. It is supposed that each synthase participates in one of the six FAS-like elongation steps required for formation of the polyketide. Module 1, 2, 3, 4, 5, and 6 participating in biosynthesis steps 1, 2, 3, 4, 5, and 6, respectively.
Biosynthesis of polyketides; acyltransferase (AT), beta-ketoacyl carrier protein synthase (KS), and acyl carrier protein (ACP) for chain elongation. Beta-ketoreductase (KR), dehydratase (DH), and enoyl reductase (ER) for processing of the beta carbon, and thioesterase (TE) for release and lactonization of the full-length chain.

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.
