- * E1-E2 ATPases phosphorylation site *
- **************************************
-
- E1-E2 ATPases are cation transport ATPases which form an aspartyl phosphate
- intermediate in the course of ATP hydrolysis. ATPases which belong to this
- family are listed below [1,2,3].
-
- - Fungal and plant plasma membrane (H+) ATPases [reviewed in 3].
- - Vertebrate (Na+, K+) ATPases (sodium pump) [reviewed in 5,6].
- - Gastric (K+, H+) ATPases (proton pump).
- - Calcium (Ca++) ATPases (calcium pump) from the sarcoplasmic reticulum (SR),
- the endoplasmic reticulum (ER) and the plasma membrane.
- - Copper (Cu++) ATPases (copper pump) which are involved in two human genetic
- disorders: Menkes syndrome and Wilson disease [7].
- - Bacterial potassium (K+) ATPases.
- - Bacterial cadmium efflux (Cd++) ATPases [reviewed in 8].
- - Bacterial magnesium (Mg++) ATPases [9].
- - A probable cation ATPase from Leishmania.
- - fixI, a probable cation ATPase from Rhizobium meliloti, involved in
- nitrogen fixation.
-
- The region around the phosphorylated aspartate residue is perfectly conserved
- in all these ATPases and can be used as a signature pattern.
-
- -Consensus pattern: D-K-T-G-T-[LIVM]-[TI]
- [D is phosphorylated]
- -Sequences known to belong to this class detected by the pattern: ALL.
- -Other sequence(s) detected in SWISS-PROT: Staphylococcus aureus DNA gyrase
- subunit B.
- -Last update: June 1994 / Pattern and text revised.
