Conteúdo: | When nitrogen-starved mycelium of Penicilium chrysogenum is incubated with relatively high concentrations of labeled hydrophobic amino acids, influx is followed by efflux of the corresponding labeled a-ketoacid. In spite of the efflux, furter transport activity is suppressed. Cell-free extracts contain a transaminase that accepts all those amino acids exhibiti ng a-ketoacid efflux. Transaminase activity is constitutive but is induced to a 2-to 3-fold higher level during a 2-hr preincubation period with a hydrophobic amino acid. Cycloheximide prevents efflux and also the induction of the transminase.
