Expert opinion: As mass-spectrometry sequencing performance is improving with better software and hardware optimizations, combined with user-friendly interfaces, de-novo protein sequencing becomes imperative in shotgun proteomic studies. Issues regarding unknown or mutated peptide sequences, as well as, ...
De novo peptide sequencingHybrid peptide sequencingMS validationMS evidenceFunctional annotationHigh resolution mass spectrometry has revolutionized proteomics over the past decade, resulting in tremendous amounts of data in the form of mass spectra, being generated in a relatively short span of time. ...
We present DeepNovo-DIA, a de novo peptide-sequencing method for data-independent acquisition (DIA) mass spectrometry data. We use neural networks to capture precursor and fragment ions across m/z, retention-time, and intensity dimensions. They are then further integrated with peptide sequence patte...
Our system integratesde novosequencing peptides, their quality scores and error-correction information from databases into a weighted de Bruijn graph to assemble protein sequences. We evaluated ALPS performance on two antibody data sets, each including a heavy chain and a light chain. The results ...
De novo peptide sequencing in an ion trap mass spectrometer coupled on-line with a capillary HPLC using 18O labeling provides a viable alternative to the method using the combination of nanospray, 18O labeling and a quadrupole/time-of-flight mass spectrometer. Seven to sixteen amino acid ...

The studies performed on noncharacterized peptides show that this method is viable for de novo sequencing. Although the derivatization method is time consuming and can result in unwanted side products, it should be regarded as a complementary aid in protein sequence analysis by mass spectrometry 40...
Efficient and facile de novo sequencing requires good quality straightforward mass spectra. Lys-N proteolysis allows significant portions of a protein to generate simplified MALDI-CID spectra without any derivatization steps. An in silico digest of all proteins in the IPI human database revealed that ...

the present work is motivated by the de novo synthesis and functional self-organization of the Min system inside liposomes. In analogy with information storage and transfer in biology, we believe that in-liposome protein production from a DNA template is a viable route to build an autonomous, se...
