regulation of GTP breakdown, regulation of GTP catabolism, regulation of GTP degradation
OBSOLETE. Any process that modulates the frequency, rate or extent of the chemical reactions and pathways resulting in the breakdown of GTP, guanosine triphosphate.
The reason for making this term obsolete is that it gets misused in cases where phosphates are simply being removed from a small molecule. We found no cases where these molecules genuinely underwent catabolism.
