Phenylmethylsulfonyl fluoride protects L-lysine transport in Schizosaccharomyces pombe against inactivation by ammonium ions.

Biochimica et biophysica acta - 30 Apr 1990

Horák J, Sychrová H, Kotyk A

Abstract excerpt

Ammonium ions inactivate the basic amino acid transport system in Schizosaccharomyces pombe in an irreversible manner. The inactivation is accompanied by a 4-fold decrease of KT of L-lysine transport, leaving its Jmax unchanged; phenylmethylsulfonyl fluoride protects the system against inactivation. In contrast, two basic amino acid transport systems in a gap1 mutant of Saccharomyces cerevisiae are influenced by...
