The enzyme threonine-phosphate decarboxylase (EC 4.1.1.81) catalyzes the chemical reaction
This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is L-threonine-O-3-phosphate carboxy-lyase [(R)-1-aminopropan-2-yl-phosphate-forming]. Other names in common use include L-threonine-O-3-phosphate decarboxylase, CobD and L-threonine-O-3-phosphate carboxy-lyase. This enzyme is part of the biosynthetic pathway to cobalamin (vitamin B12) in anaerobic bacteria such as Salmonella typhimurium and Bacillus megaterium . In the next step, (R)-1-aminopropan-2-ol is attached to adenosylcobyric acid, forming adenosylcobinamide phosphate.
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.
