(Science: enzyme) An enzyme that catalyses the hydrolysis of myosin aTP in the presence of actin to form myosin aDP and orthophosphate. This reaction is the immediate source of free energy that drives muscle contraction. In the absence of actin, myosin atpase activity is low and requires calcium ions. chingling pokemon gen 5ATPase is genetically conserved in animals; therefore, cardenolides which are toxic steroids produced by plants that act on ATPases, make general and effective animal toxins that act dose dependently. Besides exchangers, other categories of transmembrane ATPase include co-transporters and pumps Ver mais ATPases (EC 3.6.1.3, Adenosine 5'-TriPhosphatase, adenylpyrophosphatase, ATP monophosphatase, triphosphatase, SV40 T-antigen, ATP hydrolase, complex V (mitochondrial electron transport), (Ca + Mg )-ATPase, … Ver mais The Walker motifs are a telltale protein sequence motif for nucleotide binding and hydrolysis.
