Sci Rep
. 2022 Aug;
12(1):14298.
PMID: 35995915
Light-induced oxidation of the reaction center dimer and periplasmic cytochromes was detected by fast kinetic difference absorption changes in intact cells of wild type and cytochrome mutants (cycA, cytC4 and...

Sci Rep
. 2020 Aug;
10(1):14012.
PMID: 32814810
Antenna systems serve to absorb light and to transmit excitation energy to the reaction center (RC) in photosynthetic organisms. As the emitted (bacterio)chlorophyll fluorescence competes with the photochemical utilization of...

Tian Q, Smart J, Clement J, Wang Y, Derkatch A, Schubert H, et al.
Histochem Cell Biol
. 2015 Dec;
145(5):561-72.
PMID: 26708151
Ras homolog enriched in brain (RHEB1) is a member within the superfamily of GTP-binding proteins encoded by the RAS oncogenes. RHEB1 is located at the crossroad of several important pathways...

PMID: 24594058
Background: Neuronal polarization is an essential step of morphogenesis and connectivity in the developing brain. The serine/threonine kinase LKB1 is a key regulator of cell polarity, metabolism, tumorigenesis, and is...

Endocrinology
. 2011 Feb;
152(5):1901-10.
PMID: 21343252
Arachidonic acid (AA) is generated in the anterior pituitary gland upon stimulation by the ACTH secretagogue, CRH. Using the patch clamp technique, we examined the action of AA on the...

Barkovits K, Harms A, Benkartek C, Smart J, Frankenberg-Dinkel N
FEMS Microbiol Lett
. 2008 Feb;
280(2):160-8.
PMID: 18248420
Phytochromes are red/far-red light photoreceptors found in plants, cyanobacteria and heterotrophic bacteria. Biochemical analyses have established that the genes bphO and bphP (PA4116 and PA4117) of Pseudomonas aeruginosa encode both...

J Bacteriol
. 2007 Jul;
189(21):7765-73.
PMID: 17616588
We provide in vivo genetic and in vitro biochemical evidence that RegA directly regulates bacteriochlorophyll and carotenoid biosynthesis in Rhodobacter capsulatus. beta-Galactosidase expression assays with a RegA-disrupted strain containing reporter...

Smart J, Tolle V, Otero-Corchon V, Low M
Endocrinology
. 2006 Nov;
148(2):647-59.
PMID: 17095588
Proopiomelanocortin (POMC) is synthesized predominantly in pituitary corticotrophs, melanotrophs, and arcuate hypothalamic neurons. Corticotroph-derived ACTH mediates basal and stress-induced glucocorticoid secretion, but it is uncertain whether POMC peptides produced in...

J Bacteriol
. 2006 Feb;
188(4):1567-76.
PMID: 16452440
We demonstrate that the expression of hem genes in Rhodobacter capsulatus is transcriptionally repressed in response to the exogenous addition of heme. A high-copy suppressor screen for regulators of hem...

J Clin Invest
. 2006 Jan;
116(2):495-505.
PMID: 16440060
Null mutations of the proopiomelanocortin gene (Pomc) cause obesity in humans and rodents, but the contributions of central versus pituitary POMC deficiency are not fully established. To elucidate these roles,...
