| Abstract |
A novel, inducible carbon-phosphorus bond cleavage enzyme, phosphonopyruvate hydrolase, was detected in cell-free extracts of Burkholderia cepacia Pal6, an environmental isolate capable of mineralising L-phosphonoalanine as carbon, nitrogen and phosphorus source. The activity was induced only in the presence of phosphonoalanine, did not require phosphate starvation for induction and was uniquely specific for phosphonopyruvate, producing equimolar quantities of pyruvate and inorganic phosphate. The native enzyme had a molecular mass of some 232 kDa and showed activation by metal ions in the order Co2+ > Ni2+ > Mg2+ > Zn2+ > Fe2+ > Cu2+. Temperature and pH optima in crude cell extracts were 50 degrees C and 7.5, respectively, and activity was inhibited by EDTA, phosphite, sulfite, mercaptoethanol and sodium azide. Phosphonopyruvate hydrolase is the third bacterial C-P bond cleavage enzyme reported to date that proceeds via a hydrolytic mechanism. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. 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 21 May 2013.
All research outputs
#7,454,066
of 22,788,370 outputs
Outputs from Archives of Microbiology
#568
of 2,770 outputs
Outputs of similar age
#24,271
of 107,670 outputs
Outputs of similar age from Archives of Microbiology
#2
of 8 outputs
Altmetric has tracked 22,788,370 research outputs across all sources so far. This one is in the 44th percentile – i.e., 44% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,770 research outputs from this source. They receive a mean Attention Score of 3.7. This one is in the 42nd percentile – i.e., 42% of its peers scored the same or lower than it.
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 107,670 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 18th percentile – i.e., 18% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 8 others from the same source and published within six weeks on either side of this one. This one has scored higher than 6 of them.
