Combatting hospital-acquired infections with protein metal complex

A protein containing a metal complex for blue paint inhibits growth of a pathogenic bacterium through iron deprivation

Abstract:

Professor Yoshihito Watanabe (WPI-ITbM, Cooperating Researcher), Associate Professor Osami Shoji, Ms. Chikako Shirataki of Nagoya University and co-workers have found a new method using an artificial metalloprotein (a protein that contains a metal) to inhibit the growth of Pseudomonas aeruginosa bacteria, which is a common bacterium that can cause diseases in humans and evolves to exhibit multiple antibiotic resistance. The inhibition of growth has been achieved through the deprivation of iron uptake using an artificial metalloprotein.
