ATP binding domain 4 Functions

ATP Binding domain 4 proteins - shows little homology with human protein, and the % sequence ID = 36.8% - under the family of AAHN-like super family

My sequences:

putative n-type ATP pyrophosphatase from Pyrococcus furiosus, the Northeast Structural Genomics Target PfR23

- ATP pyrophosphatase (ATP PPase) is used to assist lysidine formation using a lysine-specific loop and tRNA recognition domain - Lysidine is a lysine-combined modified cytidine, locating at antcodon wobble position (34) of bacterial tRNA - Usually ATP-pyrophosphatatse has a domain of GMP synthetase, for adding adenine and help lysine attack on Carbon atom. http://www.pnas.org/content/102/21/7487.abstract
