| Abstract: | A factor capable of the reversible inactivation of PAL in vitro has been demonstrated in extracts of gherkin hypocotyls. Kinetics of the interaction between enzyme and inactivator indicate that PAL and the factor form a freely reversible complex. The properties of the inactivator are discussed in relation to its proposed role in the regulation of PAL activity in dark- and light-grown tissue. |
