Kinetic studies and characteristics of a modifier of Ca2+-stimulated ATPase
Abstract:
1. The thermostable modifier increases the Mg2+-stimulated ATPase with a parallel decrease of Ca2+-stimulated ATPase. 2. The modifier inhibited Ca2+-stimulated ATPase by diminishing the velocity without any significant effect on the apparent affinity of binding of Ca2+. 3. The inhibition of Ca2+-stimulated ATPase was independent of Ca2+ concentration and could not be reversed by increasing Ca2+ levels. 4. Monovalent cations and calmodulin increased the Mg2+-stimulated ATPase in the presence of the modifier.

ATP Driven Pumps I: An Overview
There are four main types of ATP-driven pumps - P-type, V-type, F-type, and ABC transporter. All these pumps are of varying complexities and are...

ATP Driven Pumps II: P-type Pumps
A typical P-type pump has three cytosolic domains: nucleotide-binding (N), phosphorylation (P), and activator (A) domains. These domains are connected to the membrane-spanning helices by short amino acid segments. ATP hydrolysis and covalent phosphoenzyme intermediate formation are crucial parts of the catalytic cycle. At the highly...
