The Amino Acid Sequence of Cytochrome b,*
نویسنده
چکیده
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 chymotryptic peptides the order of the tryptic peptides was established. This information, combined with the known sequences of the tryptic peptides, provided sufficient evidence to construct a unique amino acid sequence for the 85 amino acid residues in cytochrome bg.

Structural Characteristics of Stable Folding Intermediates of Yeast Iso-1-Cytochrome-c
Cytochrome-c (cyt-c) is an electron transport protein, and it is present throughout the evolution. More than 280 sequences have been reported in the protein sequence database (www.uniprot.org). Though sequentially diverse, cyt-c has essentially retained its tertiary structure or fold. Thus a vast data set of varied sequences with retention of similar structure and fun...

Infectious bronchitis (IB) virus genome codes for four structural proteins, among which the S1 subunit of spike glycoprotein comprises the major epitopes to induce neutralizing antibodies. This study involved the comparison of the full S1 sequences of five IB viruses, namely two Massachusetts and three 793/B serotypes, isolated from IB outbreaks during 2001-2002, with all other Iranian an...

Members of Nemacheilidae Family, Turcinoemacheilus genus were subjected to molecular phylogenetic analysis in this study. This genus was reported in 2009 to inhabit in Karoon River drainage, in contrary to previous assumption that it was the endemic species in the Basin of Tigris River. It was sampled from three stations placed in different tributaries in Karoon drainage and evaluated to unders...

BACKGROUND: Fasciola species are parasitic trematode with world wide distribution that infects wild and domesticated herbivores, particularly ruminants. The aim of the present study was to investigate the intra species variations of F. gigantica, from goats and buffalos isolates in two common geographic climates of Iran. METHODS: Fasciola species were collected from goat, buffalo, sheep, and ca...

Veritable identification and differentiation of avian species is a vital step in conservative, taxonomic, forensic, legal and other ornithological interventions. Therefore, this study involved the application of molecular approach to identify some avian species i.e. Chicken (Gallus gallus), Muskovy duck (Cairina moschata), Japanese quail (Coturnix japonica), Laughing dove (Streptopelia senegale...
