Cayman Cdnp (Mycobacterium Tuberculosis Strain Atcc 25618h37rv Re

Cyclic dinucleotide phosphodiesterase (CdnP) is a soluble phosphodiesterase involved in regulating cyclic dinucleotide signaling during intracellular infections of M. tuberculosis. It is composed of an N-terminal Asp-His-His (DHH) domain and a C-terminal DHH-associated (DHHA1) domain that catalyze the hydrolysis of cyclic dinucleotides. CdnP hydrolyzes a variety of cyclic dinucleotides, including cyclic di-AMP (Item No. ), cyclic di-GMP (Item No. 17144), and 2′3′-cGAMP (Item No. ), which decreases their recognition by the stimulator of interferon genes (STING), a key mediator in the host innate immune response.^,, Knockout of the gene encoding CdnP, CnpB, increases the production of IFN-β in isolated mouse bone marrow-derived macrophages (BMDMs) infected with CnpB^-/- M. tuberculosis, as well as decreases pulmonary and splenic bacterial burden and increases survival in CnpB^-/- M. tuberculosis-infected mice. Cayman’s CdnP (Mycobacterium tuberculosis strain ATCC 25618H37Rv recombinant) protein contains N-terminal Trx- and His-tags followed by a thrombin cleavage site and an S-tag followed by an enterokinase cleavage site.
