What are some of the interactions made between ATP and the kinase? Can you please describe bonds that the protein makes with (a) the phosphate groups, (b) the sugar, and (c) the adenine base? Please don't just copy answers from google.. I already read most of em.. :(
Protein phosphorylation and dephosphorylation are important regulatory mechanisms. Protein kinases attach phosphoryl groups to target proteins, while only a phosphatase removes the phosphoryl group. What does this method of covalent control cost in terms of energy?
Regarding the sodium potassium pump, I am confused which enzymes are involved in the addition of the phosphate group onto the protein to change the conformation. Is it only kinases or kinases AND ATPases? I was under the impression that kinases add organic phosphates onto molecules, while ATPases cleave ATP into ADP and a phosphate group. Would ATPase need to split the ATP molecule before the kinase can transfer the phosphate group onto the sodium potassium pump?

V-class proton pumps run backward relative to the F-class ATP synthase. Consider the cartoon, which shows the conformations of the beta-subunits and ATPIADP + Pj of the F-class synthase. Which of the following associations between the conformation of the beta subunit and ATP/ADP + P¡ is correct for V- Binding Change Mechanism loose binding ADP+P ATP ATP class pumps? C repeat ADP + P, ADP АТР tight binding АТР +P оpen АТР O The open conformation releases ATP. Hydrolysis of ATP to ADP + P¡ drives the change from tight to loose. O Binding of ADP + P¡ drives change from open to loose. Hydrolysis of ATP to ADP + Pj drives the change from open to loose.
