Starting from tert-Butyloxycarbonyl(BOC)-Anthranilic-Acid(Abz) (1), BOC-Abz-Proline-Methyl-Ester (2) is synthesized. The crystal structure of both compounds are discussed. The conformational features of the crystal structures of 2 are compared with the conformation in solution. The whole conformational area (Φ and Ψ) of the amino acid part of 2 was investigated with the semi-empirical quantummechanical method AM 1, in order to check the general availability of the influence of ester functions to depsipeptide conformations. Cyclo-anthranoyl-prolinyl (3), which had already been described in the literature, forms crystals with a high density. Two independent molecules are found in the crystal structure; these molecules have very similar conformations.

Selection Of

The determination of the best conditions for the application of the snail enzyme digestion method in the enrichment of auxotrophic mutants in Candida utilis was carried out following Box and Wilson's mathematical method. The selection procedure proposed was tested in the enrichment of auxotrophic mutants from a mutagenized culture of a wild-type strain. Mutant frequency was increased 46-fold by treatment with snail enzyme. The method also proved useful in the selection of additional auxotrophic mutations from single auxotrophs.

Qualitative Changes

Total lipids were extracted from cells of Candida utilis grown in batch, chemostat, and phased culture. Thin-layer chromatography of the extracts showed qualitative changes in the different lipid classes with growth. Gas–liquid chromatography was used to follow quantitative changes in the fatty acid constituents. Changes were found to be analogous to those previously reported for the amino acid pool, i.e., characteristic of the medium, of growth rate, and of the environment. The significance of the changes, and of the methods used to detect them, are discussed in relation to the growth and metabolism of the cell and of the culture.
