| Comments | This protein is present in multiple copies in some organisms, each one being located in a cluster involved in the degragation of a different aromatic compound. The E.coli protein showed no observable dependence on divalent metal ions (and no loss of enzyme activity by treatment with EDTA) unlike the purified Pseudomonas sp. strain CF600 and Burkholderia xenovorans aldolases. |
