Protein

Diaminopimelate decarboxylase

Gene

lysA

Organism
Escherichia coli (strain K12)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Specifically catalyzes the decarboxylation of meso-diaminopimelate (meso-DAP) to L-lysine. Is not active against the DD- or LL-isomers of diaminopimelate.3 Publications

Catalytic activityi

Meso-2,6-diaminoheptanedioate = L-lysine + CO2.3 Publications

Cofactori

pyridoxal 5'-phosphate2 Publications

Enzyme regulationi

Is activated by 2,3-dimercaptopropan-1-ol.1 Publication

Kineticsi

  1. KM=1.7 mM for meso-2,6-diaminoheptanedioate (at pH 6.8 and 37 degrees Celsius)1 Publication
  2. KM=1.07 mM for meso-2,6-diaminoheptanedioate (at pH 8)1 Publication

    pH dependencei

    Optimum pH is 6.7-6.8.1 Publication

    Pathwayi: L-lysine biosynthesis via DAP pathway

    This protein is involved in step 1 of the subpathway that synthesizes L-lysine from DL-2,6-diaminopimelate.1 Publication
    Proteins known to be involved in this subpathway in this organism are:
    1. Diaminopimelate decarboxylase (lysA)
    This subpathway is part of the pathway L-lysine biosynthesis via DAP pathway, which is itself part of Amino-acid biosynthesis.
    View all proteins of this organism that are known to be involved in the subpathway that synthesizes L-lysine from DL-2,6-diaminopimelate, the pathway L-lysine biosynthesis via DAP pathway and in Amino-acid 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.
