Special Issue Information
Dear Colleagues,
Following the first three-dimensional structure determination of hen egg-white lysozyme in 1965 nearly two-third of ~190,000 crystal structures currently housed in the Protein Data Bank are represented by enzymes often complexed with their substrates. Fine-tuned dynamic motions regulate the enzymatic catalysis towards specific substrate molecules. Macromolecular crystallography (MX) offers highly informative snapshots of the enzyme in action although it is not an easy task to trap substrates, reaction intermediates, or products in active conformation. These snapshots are challenged by technical aspects because single pictures of the enzyme are an average of the irradiated crystal volume and time of data collection. State-of-the-art of structural biology offers a combination of macromolecular crystallography (MX), Laue diffraction, and emerging technique of Mix-and-Inject Serial Crystallography (MISC) at X-ray free-electron laser (XFEL) sources for real-time enzyme catalysis in protein crystals. Catalysis in protein crystals represents a major research trend in structural biology and the present Special Issue aims to cover its frontier technologies and methodologies, as well as novel mechanisms and applications.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
