Protein

4,5-DOPA dioxygenase extradiol

Gene

ygiD

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

Functioni

In vitro, opens the cyclic ring of dihydroxy-phenylalanine (DOPA) between carbons 4 and 5, thus producing an unstable seco-DOPA that rearranges nonenzymatically to betalamic acid. The physiological substrate is unknown.1 Publication

Miscellaneous

Betalamic acid is the structural unit of the betalains, natural nitrogen-containing water-soluble pigments with high colorant and bioactive properties, characteristic of plants of the order Caryophyllales.1 Publication

Caution

It is uncertain whether Met-1 or Met-10 is the initiator.Curated

Catalytic activityi

L-dopa + O2 = 4-(L-alanin-3-yl)-2-hydroxy-cis,cis-muconate 6-semialdehyde.1 Publication
