Serine proteases and their natural protein inhibitors are among the most intensively studied
protein complexes. About 20 structurally diverse inhibitor families have been identified …

The hematophagy behavior has evolved independently several times within the Arthropoda
phylum. Interestingly, the process of acquiring a blood meal in ticks is considerably distinct …

Correlations between amide proton temperature coefficients (Δσ HN/ΔT) and hydrogen
bonds were investigated for a data set of 793 amides derived from 14 proteins. For amide …

The aspartic proteases, also called aspartyl and aspartate proteases or acid proteases (EC
3.4. 23), belong to the endopeptidase family and are characterized by the conserved …

The last three decades of research into tick salivary components have revealed several
proteins with important pharmacological and immunological activities. Two primary interests …

Entomopathogenic fungi, such as Beauveria bassiana, penetrate the insect cuticle using a
plethora of hydrolytic enzymes including cuticle-degrading proteases and chitinases, which …

Analysis of amide proton temperature coefficients (ΔσHN/ΔT) in human ubiquitin shows their
usefulness in indicating hydrogen bonds. The availability of a very accurate solution …

Background Sexual reproduction in animals requires the production of highly specialized
motile sperm cells that can navigate to and fertilize ova. During sperm differentiation …

Insect-derived Kazal-type serine protease inhibitors exhibit thrombin, elastase, plasmin,
proteinase K, or subtilisin A inhibition activity, but so far, no functional roles for bee-derived …

Chymotrypsins (CTP) are a main type of proteolytic digestive enzymes in Lepidopteran
insects. They can play a major role in degrading activated Bt toxin in some insect species …
