Coenzyme Q2 is a universal substrate for the measurement of respiratory chain enzyme activities in trypanosomatids.

Petra Čermáková et al.

Parasite (Paris, France), 26, 17-17 (2019-03-23)

The measurement of respiratory chain enzyme activities is an integral part of basic research as well as for specialized examinations in clinical biochemistry. Most of the enzymes use ubiquinone as one of their substrates. For current in vitro measurements, several

Metabolism of long-chain fatty acids affects disulfide bond formation in Escherichia coli and activates envelope stress response pathways as a combat strategy.

Kanchan Jaswal et al.

PLoS genetics, 16(10), e1009081-e1009081 (2020-10-21)

The envelope of gram-negative bacteria serves as the first line of defense against environmental insults. Therefore, its integrity is continuously monitored and maintained by several envelope stress response (ESR) systems. Due to its oxidizing environment, the envelope represents an important

Role of the isoprenyl tail of ubiquinone in reaction with respiratory enzymes: studies with bovine heart mitochondrial complex I and Escherichia coli bo-type ubiquinol oxidase.

K Sakamoto et al.

Biochemistry, 37(43), 15106-15113 (1998-10-28)

The hydrophobic isoprene tail of ubiquinone-2 (Q2) exihibits binding specificity in redox reactions with bovine heart mitochondrial complex I (Ohshima, M., Miyoshi, H., Sakamoto, K., Takegami, K., Iwata, J., Kuwabara, K., Iwamura, H., and Yagi, T. (1998) Biochemistry 37, 6436-6445)

Roseivivax pacificus sp. nov., isolated from deep-sea sediment.

Yue-Hong Wu et al.

International journal of systematic and evolutionary microbiology, 63(Pt 12), 4574-4579 (2013-08-03)

A Gram-stain-negative, short-rod-shaped bacterium, designated 22DY03(T), was isolated from a sediment sample collected from the East Pacific Rise. The isolate required NaCl and grew best with 3-7 % (w/v) sea salts at temperature of between 30 and 35 °C at pH

Phaeobacter aquaemixtae sp. nov., isolated from the junction between the ocean and a freshwater spring.

Sooyeon Park et al.

International journal of systematic and evolutionary microbiology, 64(Pt 4), 1378-1383 (2014-01-23)

A Gram-reaction-negative, aerobic, non-spore-forming, non-motile and rod-shaped or ovoid bacterial strain, designated SSK6-1(T), was isolated from the zone where the ocean and a freshwater spring meet at Jeju island, South Korea. Strain SSK6-1(T) grew optimally at 30 °C, at pH
