Sterile alpha and TIR motif containing 1 Is an enzyme that in humans is encoded by the SARM1 gene. It is the most evolutionarily conserved member of the Toll/Interleukin receptor-1 (TIR) family. [5] [6] SARM1's TIR domain has intrinsic NADase enzymatic activity that is highly conserved from archaea, plants, nematode worms, fruit flies, and humans.
[2] [3] Each armadillo repeat is composed of a pair of alpha helices that form a hairpin structure. Multiple copies of the repeat form what is known as an alpha solenoid structure. Examples of proteins that contain armadillo repeats include β-catenin, Sarm1 , [4] α-importin, [5] plakoglobin, [6] adenomatous polyposis coli (APC), [7] and many ...
The toll-interleukin-1 receptor (TIR) homology domain is an intracellular signaling domain found in MyD88, SARM1, interleukin-1 receptors, toll receptors and many plant R proteins. It contains three highly conserved regions, and mediates protein-protein interactions between the toll-like receptors (TLRs) and signal-transduction components.
Skeletal structural formula of Vitamin B 12.Many organic molecules are too complicated to be specified by a molecular formula.. The structural formula of a chemical compound is a graphic representation of the molecular structure (determined by structural chemistry methods), showing how the atoms are connected to one another.

The complex and diverse secondary and tertiary structure of aptamers, as shown in this schematic of an aptamer's secondary structure, is what lets them bind their target strongly and specifically. Complementary base pairing is visible in the black lines connecting some G-C and A-T bases. This is a feature of nucleic acids that does not exist in ...

Structural chemistry is a part of chemistry and deals with spatial structures of molecules (in the gaseous, liquid or solid state) and solids (with extended structures that cannot be subdivided into molecules). For structure elucidation [1] a range of different methods is used.
In the following example, recursive SMARTS notation is used to combine acid oxygen and tetrazole nitrogen in a definition of oxygen atoms that are likely to be anionic under normal physiological conditions. [$([OH][C,S,P]=O),$([nH]1nnnc1)] The SMARTS above would only match the acid hydroxyl and the tetrazole N−H.
