- ATP synthase delta subunit is a subunit of bacterial and chloroplast F-ATPase/synthase. It is known as OSCP (oligomycin sensitivity conferral protein) in mitochondrial ATPase (note that in mitochondria there is a different delta subunit, ATP synthase delta/epsilon subunit). The OSCP/delta subunit appears to be part of the peripheral stalk that holds the F1 complex alpha3beta3 catalytic core stationary against the torque of the rotating central stalk, and links subunit A of the FO complex with the F1 complex. In mitochondria, the peripheral stalk consists of OSCP, as well as FO components F6, B and D. In bacteria and chloroplasts the peripheral stalks have different subunit compositions: delta and two copies of FO component B (bacteria), or delta and FO components B and B' (chloroplasts). F-ATPases lacking this subunit generally transport sodium instead of protons. They are proposed to be called N-ATPases, since they seem to form a distinct group that is further apart from usual F-ATPases than A-ATPases are from V-ATPases. Human delta subunit of ATP synthase is coded by gene ATP5O. (en)
- A subunidade delta da ATP sintase é uma subunidade da ATPase bacteriana e dos cloroplastos, ou OSCP (Oligomycin Sensitivity Conferral Protein: proteína que confere sensibilidade à oligomicina) na ATPase mitocondrial (note-se que nas mitocôndrias existe uma subunidade delta diferente). A subunidade OSCP/delta parece fazer parte do eixo periférico que sustenta o centro catalítico alfa3beta3 do complexo F1 estacionário contra o sistema binário do eixo central rotativo, e liga a subunidade A do complexo Fo ao complexo F1. Na mitocôndria, o eixo periférico consiste em OSCP, bem como nos componentes F6, B e D do complexo Fo. Nas bactérias e nos cloroplastos, o eixo periférico têm composições diferentes de subunidades: delta e duas cópias do componente B (bactéria) do complexo Fo, ou delta e componentes B e B (cloroplastos) do complexo Fo. A subunidade delta da ATP sintase humana está codificada no gene . (pt)
