title: K+ channels activated by L-alanine transport in isolated Necturus enterocytes.
abstract: Using the patch-clamp technique, we demonstrate here the opening of K+ channels evoked by the actively transported amino acid L-alanine in isolated Necturus enterocytes. These channels had a conductance of about 30 pS and their activation was dependent on transmembrane electrical potential and cytosolic Ca2+.
