Immunological reactivity of a human immunodeficiency virus type I derived peptide representing a consensus sequence of the GP120 major neutralizing region V3 [PDF]

open access: yes, 1992
To reduce the opportunities for human immunodeficiency virus type 1 (HIV-1) to evade vaccine induced immunity, the development of subunit vaccines must focus on the characterization of immunogenic epitopes, which are major targets for the immune system ...

BRUCE: a program for the detection of transfer-messenger RNA genes in nucleotide sequences [PDF]

open access: yes, 2002
A computer program, BRUCE, was developed for the identification of transfer‐messenger RNA (tmRNA) genes. The program employs heuristic algorithms to search for a tRNAAla‐like secondary structure surrounding a short sequence encoding the tag peptide.

Solution to peptide sequencing challenge [PDF]

open access: yesAnalytical and Bioanalytical Chemistry, 2013
The cyclic peptide described is kalata B1 [1, 2] and its structure is shown in Fig. 1. The partial reduction of the cyclic peptide [2, 3] allows one to establish the disulfide connectivity. The first peptide is amino-ethylated at only {2}Cys and {5}Cys, whereas the second peptide is amino-ethylated at only {1}Cys and {4}Cys.

Immunogenic Domains and Secondary Structure of Escherichia coli Recombinant Secreted Protein Escherichia coli-Secreted Protein B

open access: yesFrontiers in Immunology, 2017
Several pathogenic bacteria are able to induce the attaching and effacing (A/E) lesion. The A/E lesion is caused by effector proteins, such as Escherichia coli-secreted protein B (EspB), responsible together with Escherichia coli-secreted protein D for ...

A Peptide Core Motif for Binding to Heterotrimeric G Protein α Subunits [PDF]

open access: yes, 2005
Recently, in vitro selection using mRNA display was used to identify a novel peptide sequence that binds with high affinity to G{alpha}i1. The peptide was minimized to a 9-residue sequence (R6A-1) that retains high affinity and specificity for the GDP ...

Self-assembly of minimal peptoid sequences [PDF]

open access: yes, 2020
Peptoids are biofunctional N-substituted glycine peptidomimics. Their self-assembly is of fundamental interest because they demonstrate alternatives to conventional peptide structures based on backbone chirality and beta-sheet hydrogen bonding.

The Carboxyl-Terminal Segment of Apolipoprotein A-V Undergoes a Lipid-Induced Conformational Change [PDF]

open access: yes, 2010
Apolipoprotein (apo) A-V is a 343-residue, multidomain protein that plays an important role in regulation of plasma triglyceride homeostasis. Primary sequence analysis revealed a unique tetraproline sequence (Pro293-Pro296) near the carboxyl terminus of ...

Artificial neural networks for the prediction of peptide drift time in ion mobility mass spectrometry

open access: yesBMC Bioinformatics, 2010
Background There is an increasing usage of ion mobility-mass spectrometry (IMMS) in proteomics. IMMS combines the features of ion mobility spectrometry (IMS) and mass spectrometry (MS).
