Hydramycin: New Antibiotic Compound from Hydra
A new antimicrobial compound has been isolated from the freshwater animal Hydra. The compound, called hydramacin-1, shares virtually no similarity with any other known antibacterial proteins except for two other antimicrobials found in leech, and has been shown in laboratory studies to be highly potent.
Hydramacin proved to be extremely effective though; in a series of laboratory experiments, this protein could kill a wide range of both Gram-positive and Gram-negative bacteria, including clinically-isolated drug-resistant strains like Klebsiella oxytoca (a common cause of nosocomial infections). Hydramacin works by sticking to the bacterial surface, promoting the clumping of nearby bacteria, then disrupting the bacterial membrane.

Grötzinger and his team also determined the 3-D shape of hydramacin-1, which revealed that it most closely resembled a superfamily of proteins found in scorpion venom; within this large group, they propose that hydramacin and the two leech proteins are members of a newly designated family called the macins.

These findings have been published in the recent issue of Journal of Biological Chemistry.
