The machine acts between two levels (working–waiting), and the working one remains active for a fixed time giving a constant force. The activation rate of the machine can be put in relationship with the available ATP concentration in the solution, which gives the necessary energy supply. The translocation time shows a monotonic behaviour as a function of the activation frequency, and the velocity follows a Michaelis–Menten (MM) law that arises naturally in this description. The estimation of the stall force of the motor follows a corrected MM law which yet is to be checked in experimental investigations. The results presented here agree with recent biological experimental findings. 000063130 536__ $$9info:eu-repo/grantAgreement/ES/MINECO/FIS2008-01240$$9info:eu-repo/grantAgreement/ES/MINECO/FIS2011-25167 000063130 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-sa$$uhttp://creativecommons.org/licenses/by-nc-sa/3.0/es/ 000063130 590__ $$a4.063$$b2012 000063130 591__ $$aPHYSICS, MULTIDISCIPLINARY$$b9 / 83 = 0.108$$c2012$$dQ1$$eT1 000063130 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000063130 700__ $$0(orcid)0000-0003-0698-6555$$aMazo, Juan José$$uUniversidad de Zaragoza 000063130 700__ $$0(orcid)0000-0002-9551-624X$$aFalo, Fernando$$uUniversidad de Zaragoza 000063130 7102_ $$12003$$2395$$aUniversidad de Zaragoza$$bDepartamento de Física de la Materia Condensada$$cFísica de la Materia Condensada 000063130 773__ $$g14 (2012), 023004 [13 pp.]$$pNew j. phys.$$tNEW JOURNAL OF PHYSICS$$x1367-2630 000063130 8564_ $$s629329$$uhttps://zaguan.unizar.es/record/63130/files/texto_completo.pdf$$yVersión publicada 000063130 8564_ $$s75130$$uhttps://zaguan.unizar.es/record/63130/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000063130 909CO $$ooai:zaguan.unizar.es:63130$$particulos$$pdriver 000063130 951__ $$a2017-10-30-13:31:08 000063130 980__ $$aARTICLE
