Purification of 2,3-dihydroxybiphenyl 1,2-dioxygenase from Pseudomonas putida OU83 and characterization of the gene (bphC).
The 2,3-dihydroxybiphenyl 1,2-dioxygenase (2,3-DBPD) of Pseudomonas putida OU83 was constitutively expressed and purified to apparent homogeneity. The apparent molecular mass of the native enzyme was 256 kDa, and the subunit molecular mass was 32 kDa. The data suggested that 2,3-DBPD was an octamer of identical subunits. The nucleotide sequence of a DNA fragment containing the bphC region was d...
متن کاملGenome sequence of the polychlorinated-biphenyl degrader Pseudomonas pseudoalcaligenes KF707.
Pseudomonas pseudoalcaligenes KF707 is a soil polychlorinated biphenyl (PCB) degrader, able to grow both planktonically and as a biofilm in the presence of various toxic metals and metalloids. Here we report the genome sequence (5,957,359 bp) of P. pseudoalcaligenes KF707, which provides insights into metabolic degradation pathways, flagellar motility, and chemotaxis.

چکیده: سرطان پستان دومین عامل مرگ مرتبط با سرطان در خانم ها است. از آنجا که سرطان پستان یک تومور وابسته به هورمون است، می تواند توسط وضعیت هورمون های استروئیدی شامل استروژن و پروژسترون تنظیم شود. استروژن نقش مهمی در توسعه و پیشرفت سرطان پستان ایفا می کند و تاثیر خود را روی بیان ژن های هدف از طریق گیرنده های استروژن اعمال می کند. اما گروه دیگری از گیرنده های هسته ای به نام گیرنده های مرتبط به ا...
15 صفحه اولPurification and crystallization of 2,3-dihydroxybiphenyl 1,2-dioxygenase.
2,3-Dihydroxybiphenyl 1,2-dioxygenase, an enzyme of the biphenyl biodegradation pathway that cleaves the first of the aromatic rings, was purified to apparent homogeneity from Pseudomonas sp. strain LB400 that had been engineered to hyperexpress the bphC gene. The enzyme had a subunit molecular mass of 33.2 kDa as determined by SDS-polyacrylamide electrophoresis. Kinetic studies indicate a KM o...
متن کاملToluene degradation by Pseudomonas putida F1. Nucleotide sequence of the todC1C2BADE genes and their expression in Escherichia coli.
The nucleotide sequence of the todC1C2BADE genes which encode the first three enzymes in the catabolism of toluene by Pseudomonas putida F1 was determined. The genes encode the three components of the toluene dioxygenase enzyme system: reductaseTOL (todA), ferredoxinTOL (todB), and the two subunits of the terminal dioxygenase (todC1C2); (+)-cis-(1S, 2R)-dihydroxy-3-methylcyclohexa-3,5-diene deh...
