Mutants of Spirulina platensis resistant to 5-fluorotryptophan, beta-3-thienyl-alanine, ethionine, p-fluorophenylalanine, or azetidine-2-carboxylic acid were isolated. Some of these mutants appeared to be resistant to more than one analog and to overproduce the corresponding amino acids. A second group was composed

When treated with the amino acid analog beta-2-DL-thienylalanine, cells of the yeast Saccharomyces cerevisiae accumulated in the G1 portion of the cell cycle at the "start" event. This G1 arrest was accompanied by a rapid decrease in the rate of
"Physiological phenylketonuria": a biochemical defect caused by delayed maturation of the phenylalanine hydroxylation pathway and by competition with the phenylalanine biosynthetic pathway.

We will be concerned with the two major differentiated cell types of filamentous cyanobacteria--the heterocyst and the akinete. The former is generally accepted to be the site of aerobic nitrogen fixation in heterocystous cyanobacteria. The latter is a spore-like cell

Faecal samples were taken from three diet-managed phenylketonuric children to determine effects of beta-2-thienylalanine (beta-2-t) on indigenous bacteria. From sample swabs, 127 anaerobes were identified and tested for beta-2-t inhibition on a phenylalanine (Phe)-free medium, Anaerobe Inhibition Test (AIT) agar.
