《蛋白质与肽通讯》出版蛋白质与肽研究的所有重要方面的信件、原始研究论文、小型评论和客座编辑的问题，包括结构研究、重组表达、功能、合成、酶学、免疫学、分子模型和药物设计的进展。稿件必须具有显著的新颖性、及时性和紧迫性，值得迅速出版。有关生物重要蛋白的结晶和初步结构测定的报告，只有在它们包括重要的新方法或处理直接重要的蛋白，以及生物重要蛋白的初步结构测定时，才予以考虑。纯理论/综述性论文应该为蛋白质/肽结构和功能的原理提供新的见解。描述计算工作的手稿应包括一些实验数据，以证实计算结果。

Protein & Peptide Letters publishes letters, original research papers, mini-reviews and guest edited issues in all important aspects of protein and peptide research, including structural studies, advances in recombinant expression, function, synthesis, enzymology, immunology, molecular modeling, and drug design. Manuscripts must have a significant element 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.
