Customized Peptide Biomaterial Synthesis via an Environment Reliant Auto Programmer Stigmergic Approach

PMCID: 5951493
PMID: 29659507
DOI: 10.3390/ma11040609
call_split See protocol

[…] the 3D structure of the protein into a primary structure with the following amino acid sequence: This primary structure of protein was broken down to 10 possible peptide fragments by α-chymotrypsin (PeptideMass-ExPASy bioinformatics resource portal). The fragments with their molecular weight are presented in . The fragments with cysteine amino acid were then stigmergized to synthesize new peptide […]


AOX1 Subfamily Gene Members in Olea europaea cv. “Galega Vulgar”—Gene Characterization and Expression of Transcripts during IBA Induced in Vitro Adventitious Rooting

Int J Mol Sci
PMCID: 5855819
PMID: 29462998
DOI: 10.3390/ijms19020597

[…] using the translated peptide corresponding to exon 1. The prediction of putative isoelectric point (pI) and the molecular weight was obtained using the freely available tool PeptideMass at the Expasy software ( […]


Alternative splicing originates different domain structure organization of Lutzomyia longipalpis chitinases

PMCID: 5722264
PMID: 29236932
DOI: 10.1590/0074-02760170179

[…] whereas in the L4 larvae sample the same antibody revealed two bands (). The molecular weight range of the observed bands was within the expected for the deduced LlChit1 isoforms predicted by Ex-PASy PeptideMass tool (LlChit1-A: 53.19 kDa, LlChit1-B: 44.05 and LlChit1-C: 53.5 kDa), considering that we did not expect forms A and C to separate in the gel. […]


MALDI Mass Spectrometry Imaging: A Novel Tool for the Identification and Classification of Amyloidosis

PMCID: 5725723
PMID: 28994248
DOI: 10.1002/pmic.201700236

[…] lace Congo red staining. We investigated 16 amyloid cases including six different types of amyloid and five different histoanatomical locations. For all cases, peptides derived from in silico digest (PeptideMass, and recently identified peptide masses, formed by tryptic on‐tissue digestion of ApoE, SAP, and VTN were detected with mass errors below 35 ppm (Table S1, Supporting Info […]


Convergent evolution of plant and animal embryo defences by hyperstable non digestible storage proteins

Sci Rep
PMCID: 5696525
PMID: 29158565
DOI: 10.1038/s41598-017-16185-9

[…] To determine PmPV1’s susceptibility to digestion by the gastrointestinal tract enzymes and proteinase K, an in silico digestion was performed using on-line software ExPaSy PeptideMass and MS-Digest (, comparing the data with BSA. The number of cutting sites was normalized to a 20 kDa subunit. […]


Automated Solid Phase Protein Modification with Integrated Enzymatic Digest for Reaction Validation: Application of a Compartmented Microfluidic Reactor for Rapid Optimization and Analysis of Protein Biotinylation

Front Bioeng Biotechnol
