Structural and functional insight into the mechanism of an alkaline exonuclease from Laribacter hongkongensis.	Alkaline exonuclease and single-strand DNA (ssDNA) annealing proteins (SSAPs) are key components of DNA recombination and repair systems within many prokaryotes, bacteriophages and virus-like genetic elements. The recently sequenced ß-proteobacterium Laribacter hongkongensis (strain HLHK9) encodes putative homologs of alkaline exonuclease (LHK-Exo) and SSAP (LHK-Bet) proteins on its 3.17 Mb genome. Here, we report the biophysical, biochemical and structural characterization of recombinant LHK-Ex ...	2011	21893587
Use of specific gene analysis to assess the effectiveness of surfactant-enhanced trichloroethylene cometabolism.	The objective of this study was to evaluate the effectiveness of in situ bioremediation of trichloroethylene (TCE)-contaminated groundwater using specific gene analyses under the following conditions: (1) pretreatment with biodegradable surfactants [Simple Green™ (SG) and soya lecithin (SL)] to enhance TCE desorption and dissolution, and (2) supplementation with SG, SL, and cane molasses as primary substrates to enhance the aerobic cometabolism of TCE. Polymerase chain reaction (PCR), denaturing ...	2011	22071259
structural characterization of the rna chaperone hfq from the nitrogen-fixing bacterium herbaspirillum seropedicae smr1.	the rna chaperone hfq is a homohexamer protein identified as an e. coli host factor involved in phage qβ replication and it is an important posttranscriptional regulator of several types of rna, affecting a plethora of bacterial functions. although twenty hfq crystal structures have already been reported in the protein data bank (pdb), new insights into these protein structures can still be discussed. in this work, the structure of hfq from the β-proteobacterium herbaspirillum seropedicae, a dia ...	2011	22154803
