Structure of atpase
All of the ATPases share a common basic structure. Each rotary ATPase is composed of two major components: F 0 /A 0 /V 0 and F 1 /A 1 /V 1. They are connected by 1-3 stalks to maintain stability, control rotation, and prevent them from rotating in the other direction. One stalk is utilized to transmit … See more 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, HCO3 … See more The Walker motifs are a telltale protein sequence motif for nucleotide binding and hydrolysis.
