AMPylation targets the rate-limiting step of BiP’s ATPase cycle for its functional inactivation
The endoplasmic reticulum (ER)-localized Hsp70 chaperone BiP contributes to protein folding homeostasis by engaging unfolded client proteins in a process that is tightly coupled to ATP binding and hydrolysis. The inverse correlation between BiP AMPylation and the burden of unfolded ER proteins suggests a post-translational mechanism for adjusting BiP's activity to changing levels of ER stress, ...
متن کاملthe effect of functional/notional approach on the proficiency level of efl learners and its evaluation through functional test
in fact, this study focused on the following questions: 1. is there any difference between the effect of functional/notional approach and the structural approaches to language teaching on the proficiency test of efl learners? 2. can a rather innovative language test referred to as "functional test" ge devised so so to measure the proficiency test of efl learners, and thus be as much reliable an...
15 صفحه اولConformational changes represent the rate-limiting step in the transport cycle of maize sucrose transporter1.
Proton-driven Suc transporters allow phloem cells of higher plants to accumulate Suc to more than 1 M, which is up to ~1000-fold higher than in the surrounding extracellular space. The carrier protein can accomplish this task only because proton and Suc transport are tightly coupled. This study provides insights into this coupling by resolving the first step in the transport cycle of the Suc tr...
متن کاملKinesin ATPase: rate-limiting ADP release.
The ATPase rate of kinesin isolated from bovine brain by the method of S.A. Kuznetsov and V.I. Gelfand [(1986) Proc. Natl. Acad. Sci. USA 83, 8530-8534)] is stimulated 1000-fold by interaction with tubulin (turnover rate per 120-kDa peptide increases from approximately equal to 0.009 sec-1 to 9 sec-1). The tubulin-stimulated reaction exhibits no extra incorporation of water-derived oxygens over...
متن کاملQuestion Is phosphofructokinase the rate - limiting step of glycolysis ?
The quantitative aspects o f the regulation of glycolytic flux are still not well established. Even though convincing evidence that phosphofructokinase (PFK) participates in the regulation of the flux has been provided only for erythrocytes (albeit hexokinase seems to be more important in this respect) s, it is accepted that PFK is the main rate-controlling enzyme of glycolysis in different tis...
