Conotoxins from cone snails are valuable in physiology research and therapeutic applications. Evolutionary mechanisms of conotoxins have been investigated in several superfamilies, but there is no phylogenetic analysis on M-superfamily conotoxins. In this study, we characterized identical sequences, gene structure, novel cysteine frameworks, functions and evolutionary mechanisms of M-superfamil...

The present study is based on oribatid mite material collected in Ethiopia 2019. A list of identified taxa, including 11 species from 10 genera and nine families, provided; these, six species, four two families are recorded for the first time fauna this country. Two new superfamily Oripodoidea described: Pilobates wachteli n. sp. (Haplozetidae); Zetorchella robertbecki (Caloppiidae).

What is it? γ-Tubulin is a member of the tubulin superfamily and is required for nucleating the polymerization of microtubules in vivo. Microtubules are dynamic cytoskeletal polymers that assemble from two other members of the tubulin superfamily, α-tubulin and βtubulin. Microtubules make up the mitotic and meiotic spindles, and are important for establishing cell polarity and vesicle trafficki...

The amino acid-polyamine-organocation (APC) superfamily has been shown to include five recognized families, four of which are specific for amino acids and their derivatives. Recent high-resolution X-ray crystallographic data have shown that four additional transporter families (BCCT, TC No. 2.A.15; SSS, 2.A.21; NSS, 2.A.22; and NCS1, 2.A.39), transporting a wide range of solutes, exhibit suffic...

The present study is based on oribatid mite materials collected from leaf litter in two forest locations Cuba. A list of 64 species, belonging to 47 genera and 31 families, presented. Of these, one genus species are recorded for the first time Neotropical region; 17 subgenus, six genera, families Two new superfamily Oripodoidea—Lagenobates fossatus Ermilov Kontschán n. sp. (Haplozetidae) Mulier...

The histidine phosphatase superfamily is a large functionally diverse group of proteins. They share a conserved catalytic core centred on a histidine which becomes phosphorylated during the course of the reaction. Although the superfamily is overwhelmingly composed of phosphatases, the earliest known and arguably best-studied member is dPGM (cofactor-dependent phosphoglycerate mutase). The supe...
