NettetMotor proteins that translocate directionally on a linear lattice have been studied extensively. Such motor proteins couple the energy derived from NTP binding and hydrolysis to mechanical movement. Enzymes such as kinesin translocate directionally on microtubules (Block et al., 1990; Howard et al., 1989; Vale and Fletterick, 1997).

Kinesins move along microtubule (MT) filaments and are powered by the hydrolysis of adenosine triphosphate (ATP) (thus kinesins are ATPases, a type of enzyme). The active movement of kinesins supports several cellular functions including mitosis, meiosis and transport of cellular cargo, such as in axonal transport, and intraflagellar transport. Most kinesins walk towards the pl… oswestry handyman \\u0026 gardening servicesNettetSummary. Kinesins are ATP-dependent motor proteins that can generate force and displacement along microtubules. They play key roles in mitosis and in the trafficking of organelles and vesicles. Shortly after kinesin’s discovery in 1985, techniques were developed to measure the properties of individual proteins. rock creamery
