dimer | an unusual asymmetric dimer, with three domains for each chain, the C-terminal domain harbors the nicotinamide mononucleotide deamidase activity. The asymmetry in the CinA dimer arises from two alternative orientations of the N-terminal COG1058 domains, only one of which forms a contact with the KH-type domain from the other chain, effectively closing the active site into, we propose, a catalytically competent state | Thermus thermophilus |

General Information | Comment | Organism |
---|---|---|
evolution | the enzyme's N-terminal domain belongs to the COG1058 family and is associated with the ADP-ribose pyrophosphatase activity | Thermus thermophilus |
metabolism | the enzyme is associated with natural competence and is proposed to have a function as an enzyme participating in the pyridine nucleotide cycle, which recycles products formed by non-redox uses of NAD+ | Thermus thermophilus |
