Pathwayi: acetyl-CoA biosynthesis

This protein is involved in step 1 of the subpathway that synthesizes acetyl-CoA from acetate.UniRule annotation
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. Acetate kinase (ackA)
  2. Phosphate acetyltransferase (Sfum_1472)
This subpathway is part of the pathway acetyl-CoA biosynthesis, which is itself part of Metabolic intermediate biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes acetyl-CoA from acetate, the pathway acetyl-CoA biosynthesis and in Metabolic intermediate biosynthesis.

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.
