Among these, peptide mass fingerprinting (PMF) stands out as a pivotal method, fundamentally changing how scientists approach protein identification.Rapid identification of proteins by peptide-mass fingerprinting This technique, often referred to as protein fingerprinting, offers a faster and more efficient alternative to traditional methods like N-terminal sequencing.

At its core, peptide mass fingerprinting is a high-throughput analytical method that leverages the distinct masses of peptides generated from a protein to identify it. The process typically begins with taking a small sample of the protein of interest and digesting it with a proteolytic enzyme, such as trypsinRapid identification of proteins by peptide-mass fingerprinting. This enzymatic digestion breaks down the protein into smaller fragments, or peptides. The crucial step that follows is the measurement of the masses of these peptides. These measured peptide masses are then compared against a theoretical database of protein sequences.作者：DJC Pappin·1993·被引用次数：2376—Peptide-massfingerprints can prove as discriminating as linearpeptidesequences, but can be obtained in a fraction of the time using lessprotein. A match between the experimental peptide masses and a theoretical set of masses from a known protein in the database allows for the rapid identification of proteins.

The underlying principle of peptide mass fingerprinting relies on the fact that each protein, when digested, produces a unique set of peptides with specific masses. This unique set of peptide masses acts like a "fingerprint" for that particular protein. The sensitivity of mass spectrometry (MS), particularly techniques like MALDI-TOF peptide mass fingerprinting (PMF), is crucial for accurately measuring these peptide masses. This accuracy is vital for reliable protein identification.

Beyond direct identification, PMF has found applications in characterizing post-translational modifications and detecting errors of translation. It has also been used to screen known proteins, providing valuable insights into their structure and function. PMF allows rapid protein identification and has expanded into diverse fields, including the identification of materials in cultural artifacts by comparing collagen peptide masses to databases.Rapid identification of proteins by peptide-mass fingerprinting
