Trichosporon cutaneum R57 and its L-ethionine resistant mutant NZ94 strain were investigated. The amino acid analyses of cell content of both strains were carried out. The pool of free methionine in the mutant strain is enhanced 16.5 times. The total amount of sulphur-containing amino acids in the mutant cells was significantly increased from 36.8 in the wild strain to 113.4 mg/g protein in the...

The cDNAs encoding haemagglutinin I from plasmodia of Physarum polycephalum have been cloned using PCR protocols. The composite haemagglutinin I cDNA sequence, derived from several overlapping clones from PCR fragments, spans 408 nt and the 315 bp ORF encodes a polypeptide of 104 aa without a typical signal sequence. The putative molecular mass deduced from the amino acid sequence (10,760.76 Da...

the impact of pgf2? on total proteins, free amino acids and the amino transferases in the gonads of silkworm, bombyx mori l. were investigated in the present experiment. the effect of pgf2? resulted in increase in the total protein and free amino acid contents in the gonads of silkworm larvae indicating improved structural and dynamic levels of organization. the enhanced activity levels of amin...

Quorum sensing controls the luminescence of Vibrio fischeri through the transcriptional activator LuxR and the specific autoinducer signal produced by luxI. Amino acid sequences of these two genes were analyzed using bioinformatics tools. LuxI consists of 193 amino acids and appears to contain five α-helices and six ß-sheets when analyzed by SSpro8. LuxI belongs to the autoinducer synthetase fa...

It has been known since 1920 (Johns & Finks, 1920) that the navy bean is an inferior source of protein for rats. Everson & Heckert (1944) reported that raw navy beans were injurious to rats when given at a 10% protein level. They also reported that autoclaving the beans destroyed the injurious effect. Kakade & Evans (1963a, b) confirmed this report and observed that rats given 10% protein as ra...

Sardharwalla, I. B., Fowler, B., Robins, A. J., and Komrower, G. M. (1974). Archives of Disease in Childhood, 49, 553. Detection of heterozygotes for homocystinuria: study of sulphur-containing amino acids in plasma and urine after L-methionine loading. Twelve parents of patients with homocystinuria and 12 normal control subjects were given standard L-methionine loads. Determination of plasma c...
