Four years later, Kaiser and Botstein (1986) examined the signal peptide of the same protein by inducing multiple mutations in the signal peptide region ranging from short deletions up to long substitutions.
The most common insertion or deletion event was a one amino acid-long substitution, independent of the type of secondary structure under consideration.
71 min: With the match drifting away from his side, Raymond Domenench makes a long overdue substitution.
Based on the in vitro results, SAR of this series of compounds requires an alkoxy substituent at the 6-position to be a straight and saturated chain up to three carbons long, since substitution of unsaturated and branched alkyloxy groups results in decrease in ETA antagonist activity.
A large retrospective multi-center study, NHANES I, conducted in 3825 women in the USA, showed that women under long-term substitution had one-third fewer wrinkles than non-substituted patients (Dunn et al 1997).
It would also price out serious development of a long-term substitution of oil by alternative energy sources.
While the long-term substitution potential is uncertain, it may amount to a quarter of current fuel consumption in the EU.
Patients have to be put on life-long immunoglobulin substitution therapy in order to prevent recurrent and persistent opportunistic infections.
There has recently been a flurry of interest in such "fossilised" virus sequences when it was realised that they could potentially be used to determine the long-term substitution rates of their contemporary relatives [16] [19], [30].
Such low long-term substitution rates are clearly consistent with the hypothesis that some geminivirus species might be co-diverging with either their vector or host species [13], [25].
Nevertheless, it is apparent that considerable disparities can result between long-term substitution rates and instantaneous mutation rates, with direct and indirect estimates of the latter frequently yielding high values [26] [28].
