Early in this study, an α-Amylase from Bacillus megaterium WHO (BMW) was isolated from hot springs of Ramsar (North of Iran), and its gene was cloned in E.coli. Based on its conserved sequence regions and substrate specificity, it was classified as intermediary group enzymes with the specificity of oligo-1,6-glucosidase and neopullulanase subfamilies. In the sixth conserved re...

Mitogenomes represent useful tools for investigating the phylogeny of many metazoan clades. Regarding Collembola, use mitogenomics has already shown promising results, but few published works include sufficient taxon sampling to study its evolution and systematics on a broader scale. Here, we present phylogenetic based mitogenomes 124 species from 24 subfamilies, 16 families, four orders—one mo...

Apicomplexan protist parasites utilize host sugars transported into the parasite by sugar transporter proteins for use as an energy source. We performed a phylum-wide phylogenetic analysis of the apicomplexan sugar transporter repertoire. Phylogenetic analyses revealed six major subfamilies of apicomplexan sugar transporters. Transporters in one subfamily have undergone expansions in Piroplasma...

Membrane/ protein trafficking in the secretory/ biosynthetic and endocytic pathways is mediated by vesicles. Vesicle trafficking in eukaryotes is regulated by a class of small monomeric GTPases the Rab protein family. Rab proteins represent the largest branch of the Ras superfamily GTPases, and have been concerned in a variety of intracellular vesicle trafficking and different intracellular sig...

Living opossums (Didelphidae) comprise 125 species in 18 genera and 4 subfamilies. This synopsis lists all the didelphid taxa (subfamilies, tribes, genera, subgenera, species) currently recognised as valid, summarizes information about typification, synonyms, geographic distributions, remarks noteworthy recent changes usage, comments on still outstanding problems. A concluding discussion reject...

The repertoire of biosynthetic enzymes found in an organism is an important clue for elucidating the chemical structural variations of various compounds. In the case of fatty acids, it is essential to examine key enzymes that are desaturases and elongases, whose combination determine the range of fatty acid structures. We systematically investigated 56 eukaryotic genomes to obtain 275 desaturas...

Papain-like cysteine proteases (PLCPs) are a large class of proteolytic enzymes associated with development, immunity, and senescence. Although many properties have been described for individual proteases, the distribution of these characteristics has not been studied collectively. Here, we analyzed 723 plant PLCPs and classify them into nine subfamilies that are present throughout the plant ki...
