Engineering proteinase K using machine learning and synthetic genes
BACKGROUND Altering a protein's function by changing its sequence allows natural proteins to be converted into useful molecular tools. Current protein engineering methods are limited by a lack of high throughput physical or computational tests that can accurately predict protein activity under conditions relevant to its final application. Here we describe a new synthetic biology approach to pro...
متن کاملSpecificity of rabbit antibodies elicited by related synthetic peptides.
Three 17-residue peptides, presenting from 65% to 70% sequence homology, and one endecapeptide, with no apparent homology with the first three, were chemically synthesized and investigated in their ability to elicit rabbit antipeptide antibodies. The complex cross reactivities of the antisera were investigated by testing the binding of the antibodies to the intact peptides, to their enzymatic f...
متن کاملCleavage specificity on synthetic peptide substrates of human rhinovirus 2 proteinase 2A.
Proteinase 2A of human rhinovirus serotype 2 (HRV2 2A) was expressed in Escherichia coli and partially purified; the preparation was used to study various enzymatic parameters. Using a 16-amino acid peptide representing the native cleavage region of HRV2 2A, an apparent Km value of 5.4 x 10(-4) mol/liter was determined. A minimum of 9 amino acids (comprising residues P8 to P1') was necessary fo...
متن کاملSpecificity determinants for the AMP-activated protein kinase and its plant homologue analysed using synthetic peptides.
Inspection of sequences around sites phosphorylated by the AMP-activated protein kinase (AMP-PK), and homologous sequences from other species, indicates conserved features. There are hydrophobic residues (M, V, L, I) at P-5 and P+4, and at least one basic residue (R, K, H) at P-2, P-3 or P-4. The importance of these residues has been established for AMP-PK and its putative plant homologue using...
متن کاملSubstrate Specificity of Transglutaminases for Gluten Peptides
Background: Celiac disease is a T-cell mediated chronic inflammatory disorder of the gut that is induced by dietary exposure to gluten proteins. CD4+ T cells of the intestinal lesion recognize gluten peptides in the context of HLA-DQ2.5 or HLA-DQ8 and the gluten derived peptides become better T-cell antigens after deamidation catalyzed by the enzyme transglutaminase 2 (TG2). In this study we ai...
