✦ Synopsis

The response of three amino acid biosynthetic enzymes, threonine dehydratase, tyrosine aminotransferase and saccharopine dehydrogenase, to conditions of histidine, tryptophan or lysine limitation was investigated in I5 yeast species. The activities of all these enzymes increascd about two-to fourfold as a result of action of the general control of amino acid biosynthesis in Brerranomyces anomalus, Candida maliosa, Hansenula poly- morpha, Rhodosporidium roruloides, Saccharomyces cerevisiae and Yarrowia lipolytica. N o evidence for the existence of the general control was found in Candida brumpiii, Candida urilis, Hansenula anomala, Hansenula henricii. Kluyveromyces marxianus, Pichia guilliermondii, Saccharomycopsis capsularis, Trichosporon adeninovorans and Trigonopsis variabilis.
