Mipartoxin-I

Mipartoxin-I is a neurotoxin produced by Micrurus mipartitus, a venomous coral snake distributed in Central and South America.

[1] The toxin is produced by the Micrurus mipartitus, also known as the ‘redtail coral snake’, ‘rabo de ají’, or ‘gargantilla’.

[2] The snake populates Nicaragua, Costa Rica, isthmus of Panama, Ecuador, Colombia, Venezuela and Brazil.

CTX A5, a cardiotoxin from the cobra Naja atra, shows similarities with mipartoxin-I in the predicted core region and in amino acid sequence identity (38%).

However, the similarity in amino acid sequence of related toxins of two South American coral snakes were high (M. frontalis 70% and M. altirostris 68%).
