Witryna3.2 Inosine monophosphate dehydrogenase. IMPDH is also tightly regulated and catalyzes the conversion of IMP into xanthosine 5′-monophosphate, which is the rate-limiting step in the de novo synthesis of guanine nucleotides ( Fig. 2.2) ( Jackson et al., 1975; Weber et al., 1996 ). IMPDH exists as two 55 kDa isoforms, IMPDH1 and …
WitrynaFunction [ edit] IMP dehydrogenase 1 acts as a homotetramer to regulate cell growth. IMPDH1 is an enzyme that catalyzes the synthesis of xanthine monophosphate (XMP) from inosine-5'-monophosphate (IMP). This is the rate-limiting step in the de novo synthesis of guanine nucleotides.
