Fine-structural correlates of growth in hyphae of Ascodesmis sphaerospora.

abstract：:A previously undetected Bacillus subtilis aspartokinase isozyme, which we have called aspartokinase III, has been characterized. The new isozyme was most readily detected in extracts of cells grown with lysine, which repressed aspartokinase II and induced aspartokinase III, or in extracts of strain VS11, a mutant lack...
