Sequence analysis showed that pENO2 shares 75.6% nucleotide and 89.5% deduced amino acid sequence identity with pENO1 and is encoded by a distinct gene. | + |
The packing of the octameric enzyme in this crystal form is unusual, because the asymmetric unit contains three subunits. | + |
Cys-592, which is essential for enzymatic activity, is located in the above-mentioned histidine-rich region. | + |
From the significant sequence similarity between intradiol enzymes, it has been shown that intradiol enzymes evolved from a common ancestor. | + |
Two 2,3-dihydroxybiphenyl (23DHBP) dioxygenase genes, bphC1 and etbC involved in the degradation of polychlorinated biphenyl(s) (PCBs) have been isolated and characterized from a strong PCB degrader, Rhodococcus sp. | + |
A thermostable hydantoinase of Bacillus stearothermophilus NS1122A: cloning, sequencing, and high expression of the enzyme gene, and some properties of the expressed enzyme. | - |
A catechol 2,3-dioxygenase gene in chromosomal DNA of P. putida KF715 was cloned and its nucleotide sequence analyzed. | - |
The K+ ion activates the enzyme 100-fold with an activation constant of 6 mM, well below the physiologic concentration of K+ in E. coli. | - |
A putative regulator and its possible recognition site was suggested on the basis of homology data. | - |
The enzyme has a subunit Mr of 33,500 +/- 2000 by SDS/polyacrylamide-gel electrophoresis. | - |
