| Abstract |
In Haemophilus parasuis, the genes HAPS_0217 and HAPS_1695 are predicted to encode long-chain fatty acid-CoA ligases (FACSs). These proteins contain ATP/AMP signature motifs and FACS conserved motifs that are homologous to those in Escherichia coli FadD (EcFadD). In this study, we demonstrate that HAPS_0217 and HAPS_1695 can functionally replace EcFadD in the E. coli fadD mutant JW1794, and were thus designated fadD1 and fadD2, respectively. An evaluation of kinetic parameters indicated that FadD1 and FadD2 have a substrate preference for long-chain fatty acids. Moreover, FadD2 exhibited substrate inhibition in the presence of high concentrations of oleic acid. Single mutants of each of the fadD genes were easily constructed, whereas double mutants were not. These results were further confirmed using genomic site-directed mutagenesis, which supported the idea that H. parasuis requires either fadD1 or fadD2 for survival. The fadD1 mutant exhibited slower growth than the wild-type strain SC096, and its complementation resulted in a restored phenotype. The wild-type strain did not grow on chemically defined medium without the addition of oleic acid, indicating that lipids are a vital nutrient for this bacterium. Additionally, strains with a disrupted fadD1 gene also exhibited increased sensitivity to quinolone antibiotics, including levofloxacin, enrofloxacin, ciprofloxacin and nalidixic acid. |

Attention Score in Context
This research output has an Altmetric Attention Score of 1. 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 15 March 2017.
All research outputs
#20,410,007
of 22,959,818 outputs
Outputs from Frontiers in Cellular and Infection Microbiology
#6,029
of 6,462 outputs
Outputs of similar age
#268,726
of 308,059 outputs
Outputs of similar age from Frontiers in Cellular and Infection Microbiology
#119
of 130 outputs
Altmetric has tracked 22,959,818 research outputs across all sources so far. This one is in the 1st percentile – i.e., 1% of other outputs scored the same or lower than it.
So far Altmetric has tracked 6,462 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 5.3. This one is in the 1st percentile – i.e., 1% 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 308,059 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 130 others from the same source and published within six weeks on either side of this one. This one is in the 1st percentile – i.e., 1% of its contemporaries scored the same or lower than it.
