Motor protein systems have been of considerable interest lately. In these studies muscle contraction is modeled as the sliding of two filaments made of protein particles over one another, that is the sliding of the backbone filament on the track filament. In order to make the analytical analysis easy these filaments are assumed to be of infinite length or mass. This enables the understanding of the sliding of motility assays with constant velocity and generation of constant force. However, finite size in length and mass brings fluctuationsuctuations in velocity around certain values, and changes in direction through intermittent transitions. It is possible to associate time constants to this kind of behavior. It turns out that the magnitude of the time constant being created during the process is proportional to both the length of the filament and the mass of the protein particles.Deformation phenomenon stems from internally generated forces which so far has been examined as axonemal deformations. The elastic coupling of the protein particles to the backbone has been studied separately, which in fact is also related to the generation of internal forces. Instead of focusing on the axonemal deformations, we implemented an Ising-like potential contribution to our computation to study the elastic coupling which makes the computation easier. We found out that for certain range of parameters that measures the deformation strength, one attains a better motor because of more intense force generation at the expanse of getting a lower sliding velocity.

520 $a Motor protein sist emleri son zamanlar da buyuk ilgi toplamistir. Bu calismalarda kas kasilmasi, protein parcaaklarindan yapilmis omurga ve ray filamanlarinin biribiri uzerinde kaymasiyla modellen mi stir. Analitik an alizi kolaylastirmak icin bu filamanlarin son suz uzun luk ve kutle den olustuklari kabul edilmektedir. Bu sabit hiz ve sabit kuv vet uretimiyle hareket eden Yalniz, uzunlukta ve kutlede ki sistemin anlasilmasini kolaylastirmaktadir. sonluluk hizin belli bir deger cevre sin de degisme sine sebep olur ki bu gecisme sirasin da bu degerin isaret degistirmesine de sebep olur. Bu davranis sekline iyi bilinen Arrhenius Kanunu sayesin de bir zaman sabitit animlamak mumkundur. Meydan a cikan enerji bariyerinin buyuklugunun filamanin uzunlugu ve prot ein parcaciklarinin kutlelerinin buyukluguyle or antili oldugu ort aya cikmakt adir.Deformasyon fenomeni simdiye degin kesitsel deformasyonlar olarak in celen mis ic kuvvetlerin uretilmesiyle ort ay a cikar. Protein parcaaklarinin omurg ay a elast ik baglanmasi ayrica kuvvet uretimi ile ilgilidir. Ke sit sel deformasyonlar a odaklanmak yerine, hesaplamay a elastik bagliligi, he saplamayi daha kolay kilmakicin bir Ising benzeri pot ansiyeli katarak calistik. Deformasyon buyuklugunu olcen parametrelerin bazilari icin dusuk kayma hizlarina karsin dah a fazla kuvvet uretilmesiyle daha iyi bir motor elde e dildigini saptadik.
