Guanine-recognizing enzymes

The term Guanine-recognizing enzymes refers to a broad and heterogeneous functional class of proteins rather than a single specific therapeutic target. This group encompasses a wide variety of enzymes that interact with guanine or its derivatives, including GTPases (G proteins) involved in signal transduction, guanylate cyclases that produce second messengers, and enzymes of the purine salvage pathway such as hypoxanthine-guanine phosphoribosyltransferase (HGPRT). Because this category includes proteins with vastly different structures, localizations, and biological roles, it is considered too broad for specific drug development or target annotation. Therapeutic interventions typically focus on specific members within this class, such as KRAS in oncology or soluble guanylate cyclase in cardiovascular disease, rather than the group as a whole.
