The Southern smooth snake, Coronella girondica, is a small-sized colubrid found in Northwest Africa and Southwest Europe. Mitochondrial DNA-based studies showed that the species can be split into five clades: two from (one Moroccan one Tunisian-Algerian) three Europe south-west of Iberian Peninsula, south-east Spain rest European range). With regards to Italy, date, only samples have been analy...

The gene sequences for honeybee cytochrome b, ATPase 6, and ATPase 8 are presented, along with the inferred amino acid sequences of the proteins. These mitochondrial genes are in the same relative positions as are their counterparts in Drosophila mitochondrial mtDNA and have evolved at a significantly greater overall rate than have those of Drosophila. Comparisons using both amino acid identity...

Gelatin is a hydrocolloid widely used in food products, especially soft candy. It contains essential amino acids - except tryptophan which easily digested, not toxic, can form flexible and robust film layer to produce the right product. However, as Muslim, it must ensure that what consumed halal, from bovine gelatin. The purpose of this study was identify gelatin candy products using specific p...

Preparations enriched in Chlamydomonas reinhardtii thylakoids have proven useful in the study of photosynthesis. Many of their polypeptides however remain unidentified. We report here on three of those, h1 (34 kDa), h2 (11 kDa), and P3 (63 kDa). h1, h2, and P3 are present in all tested mutants of C. reinhardtii lacking either one or several of the photosynthetic chain complexes or depleted in t...

The complete nucleotide sequence of the mitochondrial genome of a very primitive unicellular red alga, Cyanidioschyzon merolae , has been determined. The mitochondrial genome of C.merolae contains 34 genes for proteins including unidentified open reading frames (ORFs) (three subunits of cytochrome c oxidase, apocytochrome b protein, three subunits of F1F0-ATPase, seven subunits of NADH ubiquino...

Increased contractile activity of skeletal muscle augments the volume fraction and enzymatic capacity of mitochondria and suppresses the enzymatic capacity of several cytoplasmic enzymes of glycolysis. To examine the biochemical mechanisms underlying these effects, we measured the concentrations of cytochrome b mRNA and aldolase A mRNA in tibialis anterior muscles of adult rabbits that had been...

This is the first time that direct PCR - DNA amplification without prior DNA extraction - was successfully developed and fully validated for rapid and economical simultaneous identification of six commonly consumed meat species. To achieve this, six species-specific primers were selected from previous reports and newly designed from the mitochondrial cytochrome b (cyt b), cytochrome oxidase I (...
