Protein

Bifunctional aspartate aminotransferase and L-aspartate beta-decarboxylase

Gene

asD

Organism
Pseudomonas sp.
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Bifunctional enzyme that has both L-aspartate decarboxylase and transaminase activity. Has high activity with L-aspartate, and much lower activity with D-aspartate, L-lysine and L-glutamine.2 Publications

Catalytic activityi

L-aspartate = L-alanine + CO2.
L-aspartate + 2-oxoglutarate = oxaloacetate + L-glutamate.

Cofactori

Enzyme regulationi

Inhibited by 10 mM Co2+, Mn2+ and Ni2+, and by 1 mM Cu2+ and Hg2+.1 Publication

Kineticsi

  1. KM=11 mM for L-aspartate1 Publication

    pH dependencei

    Optimum pH is 5.1 Publication

    Temperature dependencei

    Optimum temperature is 45 degrees Celsius.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.
