Amino acid composition of mycobacteria

Archives of Biochemistry and Biophysics, 1956
Abstract The amino acid composition of ten strains of mycobacteria cultured on chemically defined media has been determined by microbiological assay. It was found that glutamic acid is the most abundant amino acid, and that the relative order of abundance of the other amino acids differs somewhat from that of other microorganisms or vertebrates ...

Amino-Acid Composition of Salmine

Nature, 1949
A DETAILED chemical analysis of the amino-acid composition of salmine (from a commercial source) was presented by Block and Boiling1, who used chemical and microbiological techniques. The amino-acids found were arginine, alanine, isoleucine, proline, serine and valine. Tristram2 confirmed the presence of these, and in addition demonstrated that glycine

Amino acid compositions of proteinoids

Archives of Biochemistry and Biophysics, 1963
Abstract Proteinoids prepared by thermal copolymerization of 18 common amino acids have been analyzed. Conditions for quantitative recovery of the total amino acids following hydrolysis have been established. The effects of various amino acid reaction mixtures upon the composition of the polymers obtained have been studied.

Amino Acid Composition Determination

1970
The pioneering studies of Emil Fischer [301] at the turn of the century established the role of amino acids and the peptide bond in the composition and chemistry of proteins. In the light of contemporary techniques, his methods of protein degradation and subsequent fractionation of the products appear cumbersome and of historical interest only.

The amino acid composition of desoxyribonuclease I

Biochimica et Biophysica Acta, 1957
Abstract 1. 1. The amino acid composition of DNase I has been determined. 2. 2. On the basis of the data obtained it was calculated that one DNase I molecule contained 540 amino acid residues. 3. 3. The minimum molecular weight calculated from the amino acid composition was 61,566.

The amino acid composition of bovine prothrombin

Archives of Biochemistry and Biophysics, 1954
Abstract The full amino acid composition of bovine prothrombin has been measured by using ion-exchange chromatography. In addition, other methods were used for the estimation of tyrosine, tryptophan, phenylalanine, and amide ammonia. Cysteine-cystine were estimated as cysteic acid.

Amino acid composition in Isoparorchis hypselobagri

Zeitschrift f�r Parasitenkunde, 1976
The free amino acids of Isoparorchis hypselobagri have been determined by the chromatographic method (two-dimensional ascending). These are: leucine, valine, proline, alanine, glycine, glutamic acid and aspartic acid.

Amino-acid Composition of Prekeratin

Nature, 1964
IN a previous communication1 a new isolation technique was described by which pure prekeratin can be obtained from the epidermis of the cow's nose. For the extraction of the epidermis 0.1 M citric acid–sodium citrate buffer of pH 2.6 and ionic strength of 0.6 was used and prekeratin was isolated from the epidermal extract by serial precipitations in ...

Amino-acid Composition of Crayfish Trypsin

Nature, 1970
THE homology in primary structure of mammalian pancreatic serine proteases is well established1,2. Progress has now been made in the elucidation of the evolutionary history of this group of proteases. Neurath and his co-workers3 studied the amino-acid composition of trypsinogen isolated from the pancreas of the spiny Pacific dogfish and presented a ...
