Article Abstract
Streptococcus pyogenes protein 0843 (Spy0843) is a recently identified protein with a potential adhesin function. Sequence analysis has shown that Spy0843 contains two leucine-rich repeat (LRR) domains that mediate interactions with the gp340 receptor. Here, the C-terminal LRR domain was overexpressed in Escherichia coli, purified and crystallized in the presence of 1.7-1.8 M ammonium sulfate pH 7.4 as precipitant. Data were collected from a single crystal to 1.59 Å resolution at 100 K at a synchrotron-radiation source. The crystal was found to belong to space group I41, with unit-cell parameters a = b = 121.4, c = 51.5 Å and one molecule in the asymmetric unit. Elucidation of the crystal structure will provide insights into the interactions of Spy0843 with the gp340 receptor and a better understanding of the role of Spy0843 in streptococcal infections.

Leucine-rich glioma-inactivated 1 protein (LGI1) is a secreted neuronal protein consisting of the N-terminal leucine-rich repeat (LRR) and C-terminal epitempin-repeat (EPTP) domains. LGI1 is linked to epilepsy, a neurological disorder that can be caused by genetic mutations of genes regulating neuronal excitability (e.g.

Tolls or Toll-like receptors (TLRs) are involved in innate immunity in invertebrates and vertebrates. In this study, six Toll genes (named MnToll1-6) were found in the oriental river prawn Macrobrachium nipponense, and MnToll1-4 were newly identified. All six Tolls have a transmembrane domain and a TIR domain, containing different numbers of leucine-rich repeats (LRR), LRR C-terminal, and LRR N-terminal domains.

Leucine-rich repeat-containing G-protein-coupled receptor 5 (LGR5), also known as G-protein-coupled receptor 49 (GPR49), is a class A G-protein-coupled receptor (GPCR) that plays a pivotal role in embryonic development and functions as a marker for adult stem cells in various tissues and organs. LGR5 possesses a large extracellular domain (ecto-domain) enriched with leucine-rich repeats (LRR), primarily responsible for binding to ligands such as R-spondins. The C-terminal LRR extracellular LOOP region of LGR5 refers to the loop structure connecting the C-terminus of LGR5 to the first transmembrane helix.

Function-to-find domain (FIIND)-containing proteins, including NLRP1 and CARD8, are vital components of the inflammasome signaling pathway, critical for the innate immune response. These proteins exist in various forms due to autoproteolysis within the FIIND domain, resulting in full-length (FL), cleaved N-terminal (NT), and cleaved C-terminal (CT) peptides, which form autoinhibitory complexes in the steady state. However, the detailed mechanism remains elusive.
