摘要:
Snake venoms hydrolyze several phosphorylated substrates. However, not is clearly understood which enzyme(s) is (are) involved in these process. Here, we propose the existence of an independent ADPase activity. In addition, we studied the reactions mechanism of nucleotide hydrolysis. This system resembles membrane ecto-nucleotidases and acts with a multi enzymatic complex transforming ATP in adenosine without the accumulation of intermediates.
