1-aminocyclopropane-1-carboxylate synthase

Gene

ACS1

Organism
Nicotiana tabacum (Common tobacco)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript leveli

Functioni

Catalyzes the formation of 1-aminocyclopropane-1-carboxylate, a direct precursor of ethylene in higher plants.

Catalytic activityi

S-adenosyl-L-methionine = 1-aminocyclopropane-1-carboxylate + methylthioadenosine.

Cofactori

Pathwayi: ethylene biosynthesis via S-adenosyl-L-methionine

This protein is involved in step 1 of the subpathway that synthesizes ethylene from S-adenosyl-L-methionine.
Proteins known to be involved in the 2 steps of the subpathway in this organism are:
  1. 1-aminocyclopropane-1-carboxylate synthase (ACS1)
  2. 1-aminocyclopropane-1-carboxylate oxidase (ACO)
This subpathway is part of the pathway ethylene biosynthesis via S-adenosyl-L-methionine, which is itself part of Alkene biosynthesis.
View all proteins of this organism that are known to be involved in the subpathway that synthesizes ethylene from S-adenosyl-L-methionine, the pathway ethylene biosynthesis via S-adenosyl-L-methionine and in Alkene 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.
