New bat species found in Malaysia

Misclassification of species suggests that there is need for a revision of the taxonomic status of muricola bats.

Enzymes are often thought to be specific, catalysing only one reaction in a cell (left), but some more promiscuous enzymes have many functions and catalyse many reactions in a cell. Credit: Courtesy of Systems Biology Research Group, UC San Diego, Jacobs School of Engineering

Why are some enzymes so promiscuous?

Enzymes are meant to be specific, right?
