title: [Seasonal dynamics of the content of proteins inhibiting trypsin-like proteases in the leaves of common oak (Quercus petraea Liebl.)].
abstract: After the successive purification of proteins-inhibitors of trypsin-like proteases using the methods of chromatography on DEAE-cellulose, trypsin-agarose and sephadex G-50, their numerous forms with the values of molecular weight 3.5; 6.3; 12.5; and 25.0 kDa have been found out. From spring to autumn the increase of the absolute content of proteins-inhibitors of all types was accompanied by the change of their relative content. The more than by an order increase of general content of proteins inhibitors is discussed from the position of their stress origin as a result of the effect of unfavorable ecological factors.
