General Information

General Information Comment Organism
additional information ecto-3'-nucleotidase activity is 60fold higher than that of ecto-5'-nucleotidase in Leishmania amazonensis. Additionally, ecto-3'-nucleotidase activity is 2fold higher in virulent Leishmania amazonensis cells than in avirulent ones Leishmania amazonensis
physiological function La3'-nucleotidase plays a significant role in the generation of adenosine, which contribute to mammalian host immune response impairment and establishment of infection, possible involvement of ecto-3'-nucleotidase in cellular adhesion Leishmania amazonensis
