In enzymology, an adenosylcobinamide-phosphate guanylyltransferase (EC 2.7.7.62) is an enzyme that catalyzes the chemical reaction
Thus, the two substrates of this enzyme are GTP and adenosylcobinamide phosphate, whereas its two products are diphosphate and adenosylcobinamide-GDP.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases). The systematic name of this enzyme class is GTP:adenosylcobinamide-phosphate guanylyltransferase. Other names in common use include CobU, adenosylcobinamide kinase/adenosylcobinamide-phosphate, guanylyltransferase, and AdoCbi kinase/AdoCbi-phosphate guanylyltransferase. This enzyme participates in porphyrin and chlorophyll metabolism.
