Brain neuraminidases and gangliosides.
A number of data of kinetics nature indicate that brain neuraminidases (the cytosol and the membrane bound enzyme) recognize the physical state of gangliosidic substrate, with immediate modification of the activity. The interactions between the enzyme(s) and the different physical forms of the substrate are still to be studied at the molecular level. The knowledge of these phenomena would greatly help understanding the role played by gangliosides in the neuronal plasma membrane.
