PsaE Is Required for in Vivo Cyclic Electron Flow around Photosystem I in the Cyanobacterium Synechococcus sp. PCC 7002.

• L. Yu, Jindong Zhao, U. Muhlenhoff, Donald A Bryant, John H Golbeck
• Plant physiology
• 1993

Electron transfer rates to P700+ have been determined in wild-type and three interposon mutants (psaE-, ndhF-, and psaE- ndhF-) of Synechococcus sp. PCC 7002. All three mutants grew significantly… (More)

Choline monooxygenase, an unusual iron-sulfur enzyme catalyzing the first step of glycine betaine synthesis in plants: prosthetic group characterization and cDNA cloning.

• Bala Rathinasabapathi, Michael Burnet, +6 authors Andrew D. Hanson
• Proceedings of the National Academy of Sciences…
• 1997

Plants synthesize the osmoprotectant glycine betaine via the route choline --> betaine aldehyde --> glycine betaine. In spinach, the first step is catalyzed by choline monooxygenase (CMO), a… (More)

Recruitment of a foreign quinone into the A(1) site of photosystem I. I. Genetic and physiological characterization of phylloquinone biosynthetic pathway mutants in Synechocystis sp. pcc 6803.

• Ted W Johnson, Gaozhong Shen, +8 authors Parag R. Chitnis
• The Journal of biological chemistry
• 2000

Genes encoding enzymes of the biosynthetic pathway leading to phylloquinone, the secondary electron acceptor of photosystem (PS) I, were identified in Synechocystis sp. PCC 6803 by comparison with… (More)

Shewanella oneidensis MR-1 nanowires are outer membrane and periplasmic extensions of the extracellular electron transport components.

• Sahand Pirbadian, Sarah E Barchinger, +10 authors Mohamed Y. El-Naggar
• Proceedings of the National Academy of Sciences…

Bacterial nanowires offer an extracellular electron transport (EET) pathway for linking the respiratory chain of bacteria to external surfaces, including oxidized metals in the environment and… (More)

Protein-cofactor interactions in bioenergetic complexes: the role of the A1A and A1B phylloquinones in Photosystem I.

• Nithya Srinivasan, John H Golbeck
• Biochimica et biophysica acta
• 2009

This review focuses on phylloquinone as an indispensable link between light-induced charge separation and subsequent charge stabilization in Photosystem I (PS I). Here, the role of the polypeptide in… (More)

Shared thematic elements in photochemical reaction centers.

• John H Golbeck
• Proceedings of the National Academy of Sciences…
• 1993

The structural, functional, and evolutionary relationships between photosystem II and the purple nonsulfur bacterial reaction center have been recognized for several years. These can be classified as… (More)

The sufR gene (sll0088 in Synechocystis sp. strain PCC 6803) functions as a repressor of the sufBCDS operon in iron-sulfur cluster biogenesis in cyanobacteria.

• T. W. Wang, Gaozhong Shen, Ramakrishnan Balasubramanian, Lee McIntosh, Donald A Bryant, John H Golbeck
• Journal of bacteriology
• 2004

The suf operon is composed of four genes (sufB, sufC, sufD, and sufS) and is highly conserved in the genomes of cyanobacteria. Open reading frame sll0088 in Synechocystis sp. strain PCC 6803 is… (More)

Spinach Thylakoid Polyphenol Oxidase : ISOLATION, ACTIVATION, AND PROPERTIES OF THE NATIVE CHLOROPLAST ENZYME.

• John H Golbeck, Kirk V. Cammarata
• Plant physiology
• 1981

Polyphenol oxidase activity (E.C. 1.14.18.1) has been found in two enzyme species isolated from thylakoid membranes of spinach chloroplasts. The proteins were released from the membrane by sonication… (More)
