Edman degradation

He developed a method for sequencing proteins, the Edman degradation.

In 1950 he published his first paper using the method later known as Edman degradation, to determine the sequence of a protein.

Phenylisothiocyanate, the reagent for the Edman degradation, can also be used.

The resulting fragments were then microsequenced by an automated Edman degradation.

The two major direct methods of protein sequencing are mass spectrometry and the Edman degradation reaction.

The sequence of a protein can be determined by methods such as Edman degradation or tandem mass spectrometry.

It is also known as Edman's reagent and is used in Edman degradation.

A reaction scheme for sequencing a protein by the Edman degradation follows - some of the steps are elaborated on subsequently.

The amino sequence of the protease inhibitor was determined by using the automatic Edman degradation method.

An advantage of the Edman degradation is that it only uses 10 - 100 pico-moles of peptide for the sequencing process.

Edman degradations can be performed directly from a PVDF membrane.

This reaction is important for chemical sequencing of proteins, as the Edman degradation process is unable to sequence more than 70 consecutive residues.

The Edman degradation is a very important reaction for protein sequencing, because it allows the ordered amino acid composition of a protein to be discovered.

An artificial isothiocyanate, phenyl isothiocyanate, is used for amino acid sequencing in the Edman degradation.

The amino acid sequences determined by Edman degradation on tryptic fragments of purified aEF-1α are underlined.

Edman degradation, developed by Pehr Edman, is a method of sequencing amino acids in a peptide.

Digestion into peptide fragments Peptides longer than about 50-70 amino acids long cannot be sequenced reliably by the Edman degradation.

Methods for determining the peptide sequence include deduction from DNA sequence, Edman degradation, and mass spectrometry.

Protein sequence can be determined by Edman degradation, in which the N-terminal residues are hydrolyzed from the chain one at a time, derivatized, and then identified.

Peak fractions were sequenced by automated Edman degradation in a 477A/120A gas-liquid pulse sequencer (Applied Biosystems).

Pehr Edman (1916-1977) was a renowned biochemist who developed a method for sequencing proteins, known as the Edman degradation, and has been called the father of modern biochemistry.

A Protein Sequencer using Edman degradation was installed in 1989 quickly followed by several DNA Sequencers which were the first to use fluorescent dye terminator chemistry.

The N-terminal sequence of the toxin was determined using HP GS1000 sequence analyzer by automated Edman degradation at the Molecular Structure Facility of UC Davis.

Because the Edman degradation proceeds from the N-terminus of the protein, it will not work if the N-terminal amino acid has been chemically modified or if it is concealed within the body of the protein.
