What to know about Medical Innovation

Researchers led by Luiz Pedro Carvalho have discovered that the TB gene rv2531c encodes an enzyme that converts glutamate to GABA under stress, contradicting previous scientific assumptions. This finding may have implications for treating tuberculosis and other pathogens like malaria and leprosy.

What happened

'Known' TB gene reveals completely unexpected biological role under stress Sadie Harley Scientific Editor Robert Egan Senior Editor The complete genome of the tuberculosis bacterium was sequenced and published in 1998.

Why it matters

Since then, scientists have deciphered about two-thirds of TB's genes.

Common ground

A research group led by biochemist Luiz Pedro Carvalho, Ph.D., of The Herbert Wertheim UF Scripps Institute for Biomedical Innovation and Technology, has found that one of TB's supposedly "known" genes has a completely unexpected biological role, with…
