Pa u voću imaš vlage tj. vode, a i voće ti se jako brzo pljesnivi pa je možda ostao komadićak pa se sve proširilo...? Još više ako je temp. veća! Malo sam čitala o otrovu lycose. Ima dvije vrste tog otrova tj. lycotoxina i nisam skužila u textu previše jer ima dosta riječi koje ne razumijem pa ću prikeljit txt tu pa neka mi neko proba prevest ko bolje zna. Piše u jednoj rečenici da nema ozbiljnijih posljedica od otrova pa šta bi to značilo? Znam da ima puno txta ali dobro je kad je detaljno:
Two peptide toxins with antimicrobial activity, lycotoxins I and II, were identified from venom of the wolf spider
Lycosa carolinensis (Araneae: Lycosidae) by virtue of their abilities
to reduce ion and voltage gradients across membranes. Both peptides
were purified to homogeneity by reversed-phase liquid chromatography
and determined to have the following primary structures by Edman
microsequencing: IWLTALKFLGKHAAKHLAKQQLSKL-NH
2 for lycotoxin I
and KIKWFKTMKSIAKFIAKEQMKKHLGGE-OH for lycotoxin II. The predicted
secondary structures of the lycotoxins display amphipathic
-helix
character typical of antimicrobial pore-forming peptides. Antimicrobial
assays showed that both lycotoxins potently inhibit the growth
of bacteria (
Escherichia coli) and yeast (
Candida glabrata) at
micromolar concentrations. To verify its hypothesized pore-forming
activity, lycotoxin I was synthesized and shown to promote efflux
of Ca
2+ from synaptosomes, to cause hemolysis of erythrocytes, and to
dissipate voltage gradients across muscle membrane. The lycotoxins
may play a dual role in spider-prey interaction, functioning both
in the prey capture strategy as well as to protect the spider
from potentially infectious organisms arising from prey ingestion.
Spider venoms may represent a potentially new source of novel
antimicrobial agents with important medical implications.
