Abstract:
... Deamidation is a promising tool to improve solubility and other functional properties of food proteins. One possibility of protein deamidation is the use of a protein glutaminase (PG; EC 3.5.1.44), an enzyme that catalyzes the deamidation of internal glutamine residues in proteins to glutamic acid residues. The PG from Chryseobacterium proteolyticum is the only one described in literature to date ...

Abstract:
... 1. Sexually selected ornaments are highly variable, even among closely related species, and the ultimate causes of variation in ornament evolution are unclear, including in rare cases of female ornament expression. One hypothesis is that differences across species in female reproductive allocation may help to explain patterns of female ornament expression among insects with nuptial gifts. 2. Dance ...
