Researchers discover unique property of critical methane-producing enzyme

An unexpected discovery has given scientists a greater understanding of an important methane-producing enzyme.

A team of IGB researchers published a paper in eLife that outlined their findings on an enzyme called methyl-coenzyme M reductase, or MCR.

Their findings overturn what was previously believed to be true in the field: that a set of unique modifications present in MCR were essential to how the enzyme functions.

Team discovers how bacteria resist a 'Trojan horse' antibiotic

A new study describes how bacteria use a previously unknown means to defeat an antibiotic. The researchers found that the bacteria have modified a common “housekeeping” enzyme in a way that enables the enzyme to recognize and disarm the antibiotic.

The study appears in the Proceedings of the National Academy of Sciences.
