López-Juez, E, Nagatani, A, Tomizawa, K, Deak, M, Kern, R, Kendrick, R E, ...
A novel cDNA sequence homologous to a phytochrome B (phyB) gene that was isolated in a library from tobacco tissue has been used in an Escherichia coli expression system to raise anti-phytochrome B...

A purification procedure was devised for a low-molecular-mass (about 10-kilodalton) membrane protein from Escherichia coli that was shown to bind specifically to the chromosomal replication origin...
Malki, A, Kern, R, Kohiyama, M, Hughes, P
The replication of both ColE1-type plasmids and plasmids bearing the origin of replication of the Escherichia coli chromosome (oriC) has been shown to be inhibited by hemimethylation of adenine...
Parental strand recognition of the DNA replication origin by the outer membrane in Escherichia coli.
Herrick, J, Kern, R, Guha, S, Landoulsi, A, Fayet, O, Malki, A, ...
The outer membrane of Escherichia coli binds the origin of DNA replication (oriC) only when it is hemimethylated. We report here the results of a footprinting analysis with the outer membrane which...
Calcium-sodium antagonism on the frog's heart: a voltage-clamp study.
Benninger, C, Einwächter, H M, Haas, H G, Kern, R
1. In double sucrose-gap voltage-clamped frog atrial fibres the influence of [Ca]o and [Na]o on membrane current and contraction was investigated. 2. The slow (secondary) inward current varied with...
Membrane current and contraction in frog atrial fibres
Einwächter, H. M., Haas, H. G., Kern, R.
1. Membrane current and mechanical activity were recorded from short segments of frog atrial muscle strips using a double sucrose gap voltage clamp arrangement. Experiments were performed at 4-7° C....
