    Perfil isoenzimático de hexoquinasa y enolasa en tejidos neurales
    (Murcia: Universidad de Murcia, Servicio de Publicaciones, 1986) Delicado, E. G.; Torres, M.; Millaruelo, A.; Miras Portugal, M. T.; Facultad de Biología
    Tissues derived from the neural crest showed a characteristic distribution and activity for each glycolitic isoenzyme. The hexokinase actívity in chromaffin tissue, pheochromocytoma and melanoma was associated with the particulate fraction of the homogenate as previously described for brain hexokínase. The experimental values obtained were 1, 2.1 and 1.68 U/g respectively, corresponding to type I isoenzyme (neural isoenzyme). In spite of the hexokinase, the enolase activity ín these tissues was found in the cytosolíc fraction. The activities were 13, 25 and 110 Ulg for chromaffin tissue, pheochromocytoma and melanoma, respectively, corresponding to the r,:y hybrid form. In melanoma sorne traces of the ctct form, a non neural isoenzyme, could be detected.
