Thioredoxin: 4. Amino Acid Sequence of Peptide B

The Amino Acid Sequence of Cytochrome b,*

Calf liver microsomal apocytochrome bs was hydrolyzed with chymotrypsin and the resulting peptides were resolved on a Dowex 1 column. The isolation and partial amino acid sequences of the 10 chymotryptic peptides are described. The total amino acid composition of these peptides is equal to the sum of the residues present in the tryptic peptides. On the basis of the data obtained for the chymotr...

The amino acid sequence of a peptide containing the active center disulfide of thioredoxin reductase from Escherichia coli.

Thioredoxin is a low molecular weight protein. In the oxidized form, thioredoxin-S2, it contains a single disulfide bridge formed from the 2 half-cystine residues in the molecule (1). The reduced or dithiol form of thioredoxin, thioredoxin-(SH)z, was first identified as the hydrogen donor in the reduction of ribonucleotides to deoxyribonucleotides in Escherichia coli (2). It has now been shown ...

Neuropeptide Y: complete amino acid sequence of the brain peptide.

The amino acid sequence of neuropeptide Y, a 36-residue peptide recently isolated from porcine brain, has been determined by using high performance liquid chromatography for separation of its tryptic and chymotryptic fragments and subsequent sequence analysis of the isolated fragments by an improved dansyl Edman subtractive technique. The amino acid sequence of neuropeptide Y has been found to ...

Amino Acid Sequence Analysis of Hemagglutinin Protein of H9N2 Isolated from Broilers in Tehran in 2007

Background and Aims: Since 1998, Iranian poultry industry has been affected by avian influenza (AI) virus, subtype H9N2. The association of high mortality and case report of H5N1 and H9N2 influenza virus in wild birds in recent years raised the suspicion of a possible new genetic modified AI virus. Methods: Partial nucleotide sequences and deduced amino acid of hemagglutinin (HA) genes of 4 H9...
