IOM 2021, Блиц — Задача 27

The Blitz-contest of IOM-2021

Условие

Hydrolysis of a natural tetrapeptide with the molar mass of 402 g/mol catalyzed by carboxypeptidase yields an amino acid that is optically inactive and a tripeptide. In the presence of trypsin, the tripeptide is further hydrolyzed into alanine and a dipeptide. The dipeptide is then fully hydrolyzed to form lysine, glutamic acid, and ammonia. Determine the correct amino acid sequence in the tetrapeptide (from the amino to the carboxyl end).

For each position in a sequence, choose one of the following amino acids: Ala, Gln, Glu, Gly, Lys.
