View source for G-box

The G-box element is a [[riboswitch]] that controls different genes of purine nucleotide metabolism in  response to the presence of guanine.

Genes controlled by a G-box element:

* ''[[xpt]]''-''[[pbuX]]''
* ''[[nupG]]''
* ''[[pbuG]]''
* ''[[purE]]-[[purK]]-[[purB]]-[[purC]]-[[purS]]-[[purQ]]-[[purL]]-[[purF]]-[[purM]]-[[purN]]-[[purH]]-[[purD]]''
