Carnivorous plants are known to secrete acid proteinases to digest prey, mainly insects, for nitrogen uptake. In the present study, we have purified, for the first time, to homogeneity two acid proteinases (nepenthesins I and II) from the pitcher fluid of Nepenthes distillatoria (a pitcher-plant known locally as badura) and investigated their enzymic and structural characteristics. Both enzymes...

Biomimicry (from bio,meaning life and mimics,meaning to imitate) is the examination of nature,its model,system,process and element and then imitate these is an appropriate manner to solve human problems. Biomechanics is the study of the structure and function of biological systems such as humans, animals, plants, organs, and cells by means of the methods of mechanics. In this paper ,the behavio...

Kif7, a member of the kinesin 4 superfamily, is implicated in a variety of diseases including Joubert, hydrolethalus and acrocallosal syndromes. It is also involved in primary cilium formation and the Hedgehog signalling pathway and may play a role in cancer. Its activity is crucial for embryonic development. Kif7 and Kif27, a closely related kinesin in the same subfamily, are orthologues of th...

Salivaricin G32, a 2667 Da novel member of the SA-FF22 cluster of lantibiotics, has been purified and characterized from Streptococcus salivarius strain G32. The inhibitory peptide differs from the Streptococcus pyogenes-produced SA-FF22 in the absence of lysine in position 2. The salivaricin G32 locus was widely distributed in BLIS-producing S. salivarius, with 6 (23%) of 26 strains PCR-positi...

(0.25 mg/liter), and CaCO3(7 g/liter). Air was sparged at 10 liter/minute; agitation was set at 500 rpm; temperature was maintained at 28°C; dissolved oxygen was set to 99.9% at 0 time. The whole mash was harvested after it was incubated for 4 days. The pellet obtained by centrifugation was extracted with methanol (6 liters) and the extract, upon concentration to a volume of 1 liter, was partit...

Kyasanur Forest disease (KFD) virus is a highly pathogenic member of the family Flaviviridae producing a haemorrhagic disease in infected human beings. Despite this high pathogenicity and potential epidemiological importance, there have been relatively few detailed antigenic or molecular studies on KFD virus. The nucleotide sequences of the genes encoding the structural proteins of the virus ha...

Phospholipases D (PLDs) are principally responsible for the local and systemic effects of Loxosceles envenomation including dermonecrosis and hemolysis. Despite their clinical relevance in loxoscelism, to date, only the SMase I from Loxosceles laeta, a class I member, has been structurally characterized. The crystal structure of a class II member from Loxosceles intermedia venom has been determ...
