Structure of the PPX/GPPA phosphatase from Aquifex aeolicus in complex with the alarmone ppGpp.

Journal of molecular biology - 1 Feb 2008

Kristensen Ole, Ross Birthe, Gajhede Michael

Abstract excerpt

The crystal structure of the prototype exopolyphosphatase/guanosine pentaphosphate phosphohydrolase protein family member from Aquifex aeolicus in complex with the intracellular second messenger guanosine tetraphosphate was determined at 2.7-A resolution. The hydrolytic base is identified as E119...
