Golgi-associated phosphohydrolases in Trypanosoma brucei brucei por Grab, D.J., Webster, P., Verjee, Y., Lonsdale-Eccles, J.

“…Acid phosphatase activity was first localized by histochemical electron microscopic techniques to the flagella pocket, tubules, vesicles and trans-Golgi in Trypanosoma brucei [4], although subsequent studies suggested that acid phosphatase activity may also be found on the cell surface of T. b rhodesiense [5] and T. congolense [8]. …”
