Assessment of the Bioactive Conformation of the Farnesyltransferase Protein Binding Recognition Motif by Computational Methods

Abstract: Ras farnesyltransferase catalyzes the carboxyl-terminal farnesylation of Ras as well as other proteins involved in signal transduction processes. Previous studies demonstrated that its inhibition suppresses the activity of Ras transformed phenotypes in cultured cells, causing tumor regression in animal models. This observation led to the consideration of farnesyltransferase as a target for cancer therapy. In the present work we report the results of a computational study aimed at assessing the bioactive confor… Show more

“…The efficiency parameter,  , was computed every 100 cycles of SA, which is defined as the number of unique conformations, , found after N cycles of SA,  (N), divided by N, and adjusted by a coefficient so that the efficiency parameter is unity after the first 100 cycles performed, which completes the criterion of the iterative process (Corcho, 1999). The procedure was terminated in all cases when the calculated efficiency of the process,was at least 10% below the starting value.…”

“…The conformational search is continued until the searching procedure reaches a low level of performance in finding new low energy conformations, i.e. when the efficiency of the procedure, termed λ, is below 0.1 (Corcho et al, 1999).…”
