Ala160 and His116 residues are involved in activity and specificity of apyrase, an ATP-hydrolysing enzyme produced by enteroinvasive Escherichia coli.
Sarli S, Nicoletti M, Schippa S, Del Chierico F, Santapaola D, Valenti P, Berlutti F. Sarli S, et al. Among authors: valenti p. Microbiology (Reading). 2005 Sep;151(Pt 9):2853-2860. doi: 10.1099/mic.0.28142-0. Microbiology (Reading). 2005. PMID: 16151198
In spite of their similarity, apyrase and A-NSAPs show different substrate specificity, apyrase being able to hydrolyse nucleotide tri- and diphosphates, but not monophosphates, as well as p-nitrophenyl phosphate (pNPP), while A-NSAPs are also active towards monophosphates …
