Stimulation with bovine serum albumin (BSA) and its C-terminal amino acid l-alanine evokes spike activity from the "sugar" cell of the labellar chemosensilla in Protophormia. The presence of ATP in the BSA solution strongly enhances this effect, but is pH-dependent. On the contrary, addition of ATP to the l-alanine solution inhibits the "sugar" cell response regardless of pH. Reception mechanisms for BSA and l-alanine are discussed. © 1995.

Abstract
Stimulation with bovine serum albumin (BSA) and its C-terminal amino acid l-alanine evokes spike activity from the "sugar" cell of the labellar chemosensilla in Protophormia. The presence of ATP in the BSA solution strongly enhances this effect, but is pH-dependent. On the contrary, addition of ATP to the l-alanine solution inhibits the "sugar" cell response regardless of pH. Reception mechanisms for BSA and l-alanine are discussed. © 1995.
