In enzymology, an adenosylcobinamide-phosphate guanylyltransferase (EC 2.7.7.62) is an enzyme that catalyzes the chemical reaction
The two substrates of this enzyme are GTP and adenosylcobinamide phosphate; 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 is part of the biosynthetic pathway to cobalamin (vitamin B12) in bacteria.
1-Aminopropan-2-ol is the organic compound with the formula CH3CH(OH)CH2NH2. It is an amino alcohol. The term isopropanolamine may also refer more generally to the additional homologs diisopropanolamine (DIPA) and triisopropanolamine (TIPA).

In molecular biology, cob(I)yrinic acid a,c-diamide adenosyltransferase EC 2.5.1.17 is an enzyme which catalyses the conversion of cobalamin into one of its coenzyme forms, adenosylcobalamin. Adenosylcobalamin is required as a cofactor for the activity of certain enzymes. AdoCbl contains an adenosyl moiety liganded to the cobalt ion of cobalamin via a covalent Co-C bond.
Cobalamin biosynthesis is the process by which bacteria and archea make cobalamin, vitamin B12. Many steps are involved in converting aminolevulinic acid via uroporphyrinogen III and adenosylcobyric acid to the final forms in which it is used by enzymes in both the producing organisms and other species, including humans who acquire it through their diet.
