The chemistry of stalked barnacle adhesive (Lepas anatifera)
The results of the first chemical analysis of the adhesive of Lepas anatifera, a stalked barnacle, are presented. A variety of elements were identified in scanning electron microscopy with energy dispersive spectrometry (SEM-EDS) of the adhesive, including Na, Mg, Ca, Cl, S, Al, Si, K and Fe; however, protein-metal interactions were not detected in Raman spectra of the adhesive. Elemental signa...
متن کاملCement Proteins of the Acorn Barnacle,
Components of the proteinaceous cement secreted by barnacles have yet to be studied because of their insolubility. We solubilized and characterized the proteins of secondary cement, which is produced when the barnacle is detached from the substratum, in Megabalanus rosa. The cement was fractionated, according to its solubility in aqueous formic acid, into a soluble fraction, SF1 (2 1%); a fract...
متن کاملTick attachment cement - reviewing the mysteries of a biological skin plug system.
The majority of ticks in the family Ixodidae secrete a substance anchoring their mouthparts to the host skin. This substance is termed cement. It has adhesive properties and seals the lesion during feeding. The particular chemical composition and the curing process of the cement are unclear. This review summarizes the literature, starting with a historical overview, briefly introducing the diff...
متن کاملBarnacle cement: a polymerization model based on evolutionary concepts.
Enzymes and biochemical mechanisms essential to survival are under extreme selective pressure and are highly conserved through evolutionary time. We applied this evolutionary concept to barnacle cement polymerization, a process critical to barnacle fitness that involves aggregation and cross-linking of proteins. The biochemical mechanisms of cement polymerization remain largely unknown. We hypo...
متن کاملRickettsia slovaca in Dermacentor marginatus and Tick-borne Lymphadenopathy, Tuscany, Italy
Of 263 patients in Tuscany, Italy, from whom ticks were removed during July 2005-May 2007, five showed signs of tick-borne encephalopathy. Of the ticks, 17 were Dermacentor marginatus; 6 (35.3%) of these were identified by sequence analysis as containing Rickettsia slovaca. Tick-borne lympadenopathy occurs in this area.
