Chameleon sequences reveal structural effects in proteins representing micelle‐like distribution of hydrophobicity

FEBS Open Bio, EarlyView.
Amino acids sequence of two different proteins with the same sequence (chameleon sequence—black boxes) represent in 3D structure of the proteins different secondary structures: HHHH—helical and BBB—Beta‐structural. The chains folded in water environment adopt different III‐order structures in which the chameleon fragments appear to adopt similar status

MNM and SNM maintain but do not establish achiasmate homolog conjunction during Drosophila male meiosis.

PLoS Genetics, 2019
The first meiotic division reduces genome ploidy. This requires pairing of homologous chromosomes into bivalents that can be bi-oriented within the spindle during prometaphase I.

Universality of transition temperatures in families of copper-oxide superconductors: interlayer tunneling redux

, 2008
We revisit the interlayer tunneling theory of high temperature superconductors and formulate it as a mechanism by which the striking systematics of the transition temperature within a given homologous series can be understood.

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

FEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Homologous pairing in genetic recombination. The pairing reaction catalyzed by Escherichia coli recA protein.

Journal of Biological Chemistry, 1981
Purified recA protein, which is essential for genetic recombination of Escherichia coli, catalyzed ATP-dependent homologous pairing of double-stranded DNA and single-stranded fragments to form D-loops. When the double-stranded DNA was nicked circular DNA

YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

FEBS Open Bio, EarlyView.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

An explanation for a universality of transition temperatures in families of copper oxide superconductors

, 2004
A remarkable mystery of the copper oxide high-transition-temperature (Tc) superconductors is the dependence of Tc on the number of CuO2 layers, n, in the unit cell of a crystal.

Separation of the presynaptic and synaptic phases of homologous pairing promoted by recA protein.

Journal of Biological Chemistry, 1984
Homologous pairing of single strands with duplex DNA promoted by recA protein occurred without a lag only when the protein was preincubated with ATP and single-stranded DNA.
