Concerning the anomalous kinetic behavior of microtubules.
We have demonstrated that tubulin-GTP subunits can react with microtubule ends containing subunits with E-site-bound GDP. This observation can be taken to rule out a previous interpretation of a biphasic dependence of the rate for subunit flux into microtubules on the subunit concentration, which is based upon an assumption that GTP is required to be present in subunits at microtubule ends in o...
متن کاملConcerning the efficiency of the treadmilling phenomenon with microtubules.
Radioactive tubulin subunit incorporation into porcine and dogfish shark brain microtubules which are at steady state has been found to result primarily from a diffusional reaction, in which subunits are incorporated although there are an equal number of tubulin subunit additions to and losses from each of the two microtubule ends in a unit of time. Treadmilling is very inefficient, and the Weg...

چکیده هدف از پژوهش حاضر بررسی رابطه کیفیت زندگی کاری و رفتار شهروندی سازمانی در مدارس مقطع متوسطه پسرانه شهر تهران از دیدگاه دبیران بود. روش پژوهش حاضر توصیفی و از نوع همبستگی بود. از بین دبیران مدارس شهر تهران تعداد 380 نفر به روش نمونه گیری خوشه ای چند مرحله ای به عنوان نمونه پژوهش انتخاب شدند و با تکمیل پرسشنامه ی کیفیت زندگی کاری والتون(1975) و پرسشنامه ی رفتار شهروندی سازمانی پودساکو...
15 صفحه اولSingle-molecule observation of anomalous electrohydrodynamic orientation of microtubules.
We use fluorescence microscopy to measure the orientation and shape of microtubules-which serve as a model system for semiflexible rods-that are electrophoretically driven. Surprisingly, a bimodal orientation distribution is observed, with microtubules in either parallel or perpendicular orientations to the electric field. The occupancy of these states varies nonmonotonically with the microtubu...
