This result suggests that a single ancestral gene, or a few closely related genes, gave rise to an eclectic set of descendants within each lineage, due to a higher rate of gene turnover, gene conversion, and/or gene rearrangement than other genes in the same array.
But although they forced the turnovers, their conversion rate wasn't quite there and the Kiwis were still in touch at 26-22 behind at the main break.
Several parameters (substrate concentration, metal content in the fiber, and flow rate) have been tested for their impact on catalytic performance, measured by the turnover frequency (TOF), conversion yield or o-toluidine production, using a surface response methodology for the optimization of the process.
An important feature of gene-family evolution highlighted in this study is that, in Drosophila, gene turnover and/or gene conversion are primarily concentrated in a few tandem arrays of CPR genes.
As mentioned above, the nucleotide state of actin is paramount in controlling turnover, and the conversion of newer (ATP or ADP + Pi) actin to aged (ADP) actin determines what regions of a network are targeted for demolition.
The immobilized quaternary ammonium salt (QCl-MS41) catalysts with longer alkyl chains showed higher EC conversion and turnover number (TON).
The 0.05 mol% PMA@FeCo/GC@MSS was used in subsequent reactions owing to a reasonable turnover frequency (TOF) and conversion.
All component sensors have basically the same specifications: turnover frequency 2.3 2.9 Hz, conversion factor 13.2 V/nT at 2.3 2.9 Hz, and 1.27 V/nT at 0.1 Hz.
The initial turnover frequency of HMF conversion was an order of magnitude greater on Au catalysts compared to either Pt or Pd.
For tackling this challenge, either a low reaction temperature approach was chosen resulting in a low turnover frequency (TOF or the conversion was kept at low levels (below 30%%).
