Special Issue Information

Dear Colleagues,

Photosystem I is a large protein-cofactor super-complex fundamental component of the electron transport chain of oxygen-evolving photosynthetic organisms, and it can operate either in series with Photosystem II in the linear electron transport chain, or independently from Photosystem II in a cyclic transport. Photosystem I is known to operate with a photochemical quantum conversion yield close to the unit, which makes it a attractive system for the development of biological-mimicking artificial molecules and devices. In Photosystem I, two structurally symmetric electron transfer chains operate in electron transfer through the so-called bidirectional mechanism, which distinguishes it from both PSII and its homologue, the purple bacteria reaction centre. However, despite intense research over several decades, some of the key mechanisms concerning the primary photochemical conversion reactions, the energy of successive electron transfer cascade, and the mechanisms controlling the functionality of the two active electron transfer branches remain to be fully elucidated. Furthermore, the partners and mechanism of cyclic electron transfer in the thylakoid membranes, and the physiological role of this transport mechanism, remain to be fully established. 

This Special Issue for IJMS aims at gathering contributions aiming at improving the understanding of the molecular mechanism of light harvesting, photochemical energy conversion, electron transfer and electron transport reaction involving Photosystem I.

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. International Journal of Molecular Sciences is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. There is an Article Processing Charge (APC) for publication in this open access journal. For details about the APC please see here. 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.
