As a result, these systems, although sufficient for evaluating increased turnover, are inadequate for evaluating decreased turnover.
On the basis of our MD simulations, we designed four CYP3A4 mutants, each with putative stabilization of the CBZ molecule in a predicted productive binding mode that was aimed at increased affinity for CBZ and increased turnover of the epoxide product.
In addition, lipid rafts isolated from the brain tissues induced the formation of 4 mers of Aβ that did not convert to fibrils for prolonged periods of time [23], suggesting increased turnover time for these lipid-induced oligomers.
The TK2 variants also showed increased turnover for l-FMAU by the same magnitude, resulting in enhanced catalytic activity.
The onset of much drier, colder periods at the boundary between these two epochs and subsequent intensification of glacial cycles throughout the Pleistocene is thought to have provided important opportunities for the diversification and increased turnover of African vertebrate species, including many arid-adapted bovids [ 21, 32].
"An acquisition of [a company like] All3Media would solve problems for ITV Studios giving them increased turnover, profits and it will diversify ITV's revenue base and critically could drive formats that will sell overseas," said another industry source.
Such increased homeostatic mechanisms, both through increased cytokine levels and perhaps increased turnover rates for HSC and other progenitors, should contribute to higher chances for mutation fixation.
The decreased stability of 38 may be due in part to its increased lipophilicity (c log P = 4.6): in many instances more lipophilic compounds have been shown to be better substrates for microsomal enzymes resulting in increased turnover.
On the other hand, the mutant enzyme possesses an increased turnover number for GD4K-na, which confirms the data obtained in earlier studies for another substrate, Z-Lys-SBzl [ 11].
There is strong evidence for bone changes during OA progression: increased turnover of subchondral bone, thinning trabecular structures, sclerosis of the subchondral plate, bone marrow lesions and subchondral bone cysts [ 3, 4].
