| Abstract |
Dioxygenases induced during benzoate degradation by the actinobacterium Rhodococcus wratislaviensis G10 strain degrading haloaromatic compounds were studied. Rhodococcus wratislaviensis G10 completely degraded 2 g/liter benzoate during 30 h and 10 g/liter during 200 h. Washed cells grown on benzoate retained respiration activity for more than 90 days, and a high activity of benzoate dioxygenase was recorded for 10 days. Compared to the enzyme activities with benzoate, the activity of benzoate dioxygenases was 10-30% with 13 of 35 substituted benzoate analogs. Two dioxygenases capable of cleaving the aromatic ring were isolated and characterized: protocatechuate 3,4-dioxygenase and catechol 1,2-dioxygenase. Catechol inhibited the activity of protocatechuate 3,4-dioxygenase. Protocatechuate did not affect the activity of catechol 1,2-dioxygenase. A high degree of identity was shown by MALDI-TOF mass spectrometry for protein peaks of the R. wratislaviensis G10 and Rhodococcus opacus 1CP cells grown on benzoate or LB. DNA from the R. wratislaviensis G10 strain was specifically amplified using specific primers to variable regions of genes coding α- and β-subunits of protocatechuate 3,4-dioxygenase and to two genes of the R. opacus 1CP coding catechol 1,2-dioxygenase. The products were 99% identical with the corresponding regions of the R. opacus 1CP genes. This high identity (99%) between the genes coding degradation of aromatic compounds in the R. wratislaviensis G10 and R. opacus 1CP strains isolated from sites of remote location (1400 km) and at different time (20-year difference) indicates a common origin of biodegradation genes of these strains and a wide distribution of these genes among rhodococci. |

Attention Score in Context
This research output has an Altmetric Attention Score of 8. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 December 2016.
All research outputs
#4,369,297
of 25,373,627 outputs
Outputs from Biochemistry
#2,479
of 22,288 outputs
Outputs of similar age
#67,057
of 328,729 outputs
Outputs of similar age from Biochemistry
#16
of 169 outputs
Altmetric has tracked 25,373,627 research outputs across all sources so far. Compared to these this one has done well and is in the 82nd percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 22,288 research outputs from this source. They receive a mean Attention Score of 4.4. This one has done well, scoring higher than 88% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 328,729 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 79% of its contemporaries.
We're also able to compare this research output to 169 others from the same source and published within six weeks on either side of this one. This one has done particularly well, scoring higher than 90% of its contemporaries.
