Functional Heterogeneity of Photosystem II in Domain Specific Regions of the Thylakoid Membrane of Spinach (Spinacia oleracea L.)
John Veerman,Michael D. McConnell,Sergei Vasil'ev,Fikret Mamedov,Stenbjörn Styring,Doug Bruce +5 more
TL;DR: Kinetic modeling of the PSII fluorescence decay kinetics revealed that PSII populations in the stroma and grana margin fractions possess much slower primary charge separation rates and decreased photosynthetic efficiency when compared to PSII population in the grana stack.

A Synthetic Protein Selected for Ligand Binding Affinity Mediates ATP Hydrolysis
Chad R. Simmons,Joshua M. Stomel,Michael D. McConnell,Daniel A. Smith,Jennifer L. Watkins,James P. Allen,John C. Chaput +6 more
TL;DR: It is shown that a de novo evolved ATP binding protein, selected solely on the basis of its ability to bind ATP, mediates the regiospecific hydrolysis of ATP to ADP when crystallized with 1 equiv of ATP.

Introduction of a hydrogen bond between phylloquinone PhQA and a threonine side-chain OH group in photosystem i
Sam Mula,Michael D. McConnell,Amy Ching,Nan Zhao,Heather L. Gordon,Gary Hastings,Kevin Redding,Art van der Est +7 more
TL;DR: Molecular dynamics simulations and ONIOM type electronic structure calculations indicate that it is possible for the OH group of the Thr side chain to form an H-bond to the carbonyl oxygen atom, O(4) of the phylloquinone, and that this results in an increase in the 2-methyl hyperfine couplings as observed in the transient EPR data.

Uphill energy transfer in photosystem I from Chlamydomonas reinhardtii. Time-resolved fluorescence measurements at 77 K.
Wojciech Giera,Sebastian Szewczyk,Michael D. McConnell,Kevin Redding,Rienk van Grondelle,Krzysztof Gibasiewicz +5 more
TL;DR: It is postulated that excitation energy transfer from bulk to low-energy chlorophylls and from Bulk to reaction center chlorophyLLs are thermally activated uphill processes that likely occur via higher excitonic states of energy accepting chlorophylla.

Expression and characterization of cytochrome c 553 from Heliobacterium modesticaldum
TL;DR: Recombinant soluble cytochrome of Heliobacterium modesticaldum is comparable to the native protein, and likely lacks a discrete electrostatic binding site on the HbRC.
