Aims and Scope:Protein & Peptide Letters publishes letters, original research papers, mini-reviews, and guest-edited issues in all important aspects of protein, peptide, and proteomics research, including structural studies, advances in recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, drug design and large-scale proteomic analyses. Manuscripts must have significant elements of novelty, timeliness, and urgency that merit rapid publication. Reports of crystallization and preliminary structure determination of biologically important proteins are considered only if they include significant new approaches or deal with proteins of immediate importance, and preliminary structure determinations of biologically important proteins. Purely theoretical/review papers should provide new insight into the principles of protein/peptide structure and function. Manuscripts describing computational work should include some experimental data to provide confirmation of the results of calculations.

Protein & Peptide Letters focuses on the following key areas of protein, peptide and proteomics research:

· Advances in Recombinant Expression

· Biotechnology

· Conformational Analysis

· Chemical Synthesis

· Drug Design

· Enzymology

· Function

· Immunology

· Molecular Recognition

· Pharmacology

Protein Based Biomaterials in Environmental Sustainability, Therapy, and Diagnostics

Protein-based biomaterials have wide variety of therapeutic and diagnostic applications. Important properties of these materials are biocompatibility, biodegradability, functional versatility, and ability to interact with life. They are biodegradable so make sought after targets for environmental applications. These materials are also being investigated for increased applications in water filtration technology and waste management. Their low imunogenicity and customisation potential make them a good choice for applied Interdisciplinary applications. Proteins being natural biopolymers offer several advantages... see more
