Abstract

Zinc is an essential element in living organisms, yet little is known about how cells ensure that zinc is allocated to the correct metalloproteins. Papers in Cell and Cell Reports demonstrate that the ZNG1 family of GTPases have metallochaperone functions: they directly transfer zinc to, and thereby activate, methionine aminopeptidases that are crucial for protein modification during or after translation.
