Abstract:

Research in the field of microbiology regarding the identification of endophytic bacteria in aloe vera is still rarely carried out while many people in East Nusa Tenggara often use aloe vera to cure diseases. The purpose of this study was to identify the endophytic bacteria Aloe barbadensis miller and to determine its antibacterial ability against the growth of Staphylococcus aureus and Escsherichia coli bacteria. The research procedures included taking samples using purposive sampling method, isolating endophytic bacteria using streak plate method, testing the antibacterial potential against

Firstly, C4b acts as the binding site for C3 which, upon cleavage by C2, forms a covalent linkage with the C4b. Secondly, C4b with covalently attached C3b serves to form a high-affinity binding site for C5. Purified allotypes C4A3, C4B1 and C4A6 were used to compare the

Abstract The chimpanzee (Ch) E complement receptor type 1 (CR177) appears to be an alternatively spliced product of the Ch CR1 gene transcript. Its cDNA-derived amino acid sequence contains complement protein-repeating modules (CP) 1-6, 28, 29, and 30 in tandem and is 98.8% homologous to the corresponding regions of human (Hu) CR1. It differs from the C4b binding site of Hu CR1 only by two amino acids, Tyr for Ser37 in CP 1 and Asp for Gly79 in CP 2. However, in addition to binding C4b, Ch E binds C3b. As homologous substitution of one of these amino acids (Tyr for Ser37) was previously shown

Abstract Functional and structural studies of the activated proteins of the complement system C4b and C3b have led to the identification of cleavage products resulting from the effect of the regulatory proteins, factor I, H, and C4b binding protein (bp).

The multisubunit enzymes of the complement system that cleave C5 have many unusual properties, the most striking of which is that they acquire their specificity for C5 following cleavage of another substrate C3. C5 convertases are assemblies of two proteins C4b and C2a (classical or lectin pathways) or C3b and Bb (alternative pathway) and additional C3b molecules. The catalytic complexes (C4b, C2a or C3b, Bb) are intrinsically unstable (t1,2 = 1–3 min) and the enzymes are controlled by numerous regulatory proteins that accelerate this natural decay rate.

Here, we have mapped the functional domains of kaposica.

Abstract A key step in the elimination of invading pathogens from the body is the covalent binding of complement proteins C3b and C4b to their surface. However, many pathogens have evolved mechanisms to avoid the complement system of the host. Understanding how these mechanisms work may lead to more efficacious forms of therapy. Here we provide an insight into the molecular basis of how Streptococcus pyogenes binds human plasma C4b-binding protein (hC4BP), a complement regulatory molecule that may decrease C3b and C4b deposition on the streptococcal surface.

Complement factor B (CFB), a 95-kDa protein, is a crucial catalytic element of the alternative pathway (AP) of complement. After binding of CFB to C3b, activation of the AP depends on the proteolytic cleavage of CFB by factor D to generate the C3 convertase (C3bBb). The C3 convertase contains the catalytic subunit of CFB (Bb), the enzymatic site for the cleavage of a new molecule of C3 into C3b. In addition to its role in activating the AP, CFB has been implicated in pathological ocular neovascularization, a common feature of several blinding eye diseases, however, with somewhat conflicting re
