Where are F and V type ATPases located?

The F-type ATPases in the thylakoid membrane and in the inner mitochondrial membrane, together with V-type ATPases in the vacuolar membrane, are large multimeric protein complexes. In contrast, the plasma membrane (P-type) H + -ATPase is smaller and comprises a single polypeptide chain.

How is the regulation of V-ATPase reversible?

One widespread mechanism of V-ATPase regulation is reversible disassembly. In response to a variety of signals (Parra et al., 2014 ), the V 1 subcomplex is detached from the V o subcomplex, resulting in the inhibited V 1 and V o subcomplexes described above ( Fig. 2 ). V 1 subunit C is released from both subcomplexes.

How are H + ATPases used in the cell?

H + -ATPases are enzymes that generate or retrieve the energy stored in H + gradients ( Mitchell, 1976; Pedersen and Carafoli, 1987; Stein, 1990; Skulachev, 1994 ). These proteins couple ATP hydrolysis/synthesis to proton flow across membranes. H + -ATPases are subdivided into three distinct groups ( Fig. 2 ): Fig 2. H + -ATPases in the plant cell.

Which is the first p type ATPase to be crystallized?

The first P-type ATPase to be crystallized was SERCA1a, a sarco (endo)plasmic reticulum Ca 2+ -ATPase of fast twitch muscle from adult rabbit. It is generally acknowledged that the structure of SERCA1a is representative for the superfamily of P-type ATPases.
