Biotechnology. Atypical aminoacids VIII

Present paper discussed the question of the evolution of the tipic alpha-am inoacidic structures in connection with the lichenic basic ternary metaboli sm. The problem was considered as a dirreect consequence of the information al potentials of the two component biosystems of the symbionth, Are also pr esented compounds with structures in which the two metabolism (i.e. M-3 and M-4) are present in distinct chemical zones. All these question are presen ted from the poin of view of the evolutionary biochemistry and biochemical taxonomy.
