Mambas

The similarity of the primary structure of different sea snake venoms has already been discussed. Postsynaptic neurotoxins from Elapidae venom have been extensively studied. Elapidae include well-known snakes such as cobra, krait, mambas, coral snakes, and all Australian snakes. Like sea snake toxins, Elapidae toxins can also be grouped into short-chain (Type I) and long-chain (Type II) toxins. Moreover, two types of neurotoxins are also similar to cardiotoxins, especially in the positions of disulfide bonds. However, amino acid sequences between cardiotoxins and sea snake and Elapidae neurotoxins are quite different. In comparing the sequence of sea snake and Elapidae neurotoxins, there is a considerable conservation in amino acid sequence, but the difference is greater than among the various sea snake toxins. [Pg.339]

On comparing the activities of the five compounds for which numerical estimates are available in all three assays (synephrine, octopamine, phenylethanolamine, norepinephrine and tyramine) the rank orders of potency in the three systems are Crayfish, 1,2,3t4,5 Cockroach, 2,1,3,4,5 Locust 1,2,3t5,4. This indicates a basic similarity in the responses of these preparations. In each case it was found that ring hydroxylation of the phenylethylamine nucleus was not essential for activity, although p-hydroxylation does yield the best activity. This is particularly evident in the crayfish study where a-MAMBA (a-methylaminomethyl benzyl alcohol), the analog of synephrine which lacks ring substitution, was one of the most active compounds tested, and 3-phenylethanolamine, the corresponding analog of OA, is almost as active as OA. The base compound for this series, phenylethylamine, also shows appreciable activity, but only in the crayfish assay. [Pg.115]

The apices of the triangle represent 100 mole % of the indicated component. The tie-lines connect possible coexisting phases (i.e physically touching pairs of carbonate minerals). The numbers I-III on the tie lines represent three different possible configurations. Data from Klein and Gole (1981), as represented in Woods (1988). Figure 2.4.

Ten per cent of the snakes in the world, about 300 different species, are poisonous, and snakes are an important source of natural toxins. Poisonous snakes belong primarily to certain groups, such as that including the mamba and cobra, the vipers, and the sea snakes and another group that includes the boomslang and the mangrove. [Pg.158]
