Abstract Urease (urea amidohydrolase, EC 3.5. 1.5) is a nickel-containing enzyme produced
by plants, fungi, and bacteria that catalyzes the hydrolysis of urea into ammonia and …

The management of parasites, insect pests and vectors requests development of novel,
effective and eco-friendly tools. The development of resistance towards many drugs and …

Plants have evolved to synthesize a variety of noxious compounds to cope with unfavorable
circumstances, among which a large group of toxic proteins that play a critical role in plant …

Ureases are metalloenzymes that hydrolyze urea into ammonia and carbon dioxide. They
were the first enzymes to be crystallized and, with them, the notion that enzymes are proteins …

Lectins are a special class of proteins widely distributed in nature, which selectively
recognize and reversibly bind to carbohydrates and glycoconjugates through their binding …

The broad distribution of ureases in leguminous seeds, as well as the accumulation pattern
of the protein during seed maturation, are suggestive of an important physiological role for …

The sap sucking insects (Hemiptera), which include aphids, whiteflies, plant bugs and stink
bugs, have emerged as major agricultural pests. The Hemiptera cause direct damage by …

Background Plants have been recognized as a good source of insecticidal agents, since
they are able to produce their own defensives to insect attack. Moreover, there is a growing …

Anopheles stephensi mosquitoes, established persistent infection at high rates in adult A …

Chitinases have been implicated in fungal cell wall remodeling and play a role in
exogenous chitin degradation for nutrition and competition. Due to the diversity of these …
