Cloning, characterization, and functional expression of acs, the gene which encodes acetyl coenzyme A synthetase in Escherichia coli.
TL;DR: It is concluded that the Escherichia coli open reading frame encodes the acetate-activating enzyme, Acs, which activated acetate across a wide range of concentrations in a coenzyme A-dependent manner.

Correlation between phosphorylation of the chemotaxis protein CheY and its activity at the flagellar motor.
Rina Barak,Michael Eisenbach +1 more
TL;DR: It is concluded that nonphosphorylated CheY can interact with the flagellar switch and cause CW rotation, but that this activity is increased by at least 2 orders of magnitude by phosphorylation.

Control of bacterial chemotaxis
TL;DR: CheY phosphorylation appears to be involved in controlling both the excitation and adaptation mechanisms of bacterial chemotaxis, which is the most prominent model system for signal transduction in bacteria.
141
Identification of the binding interfaces on CheY for two of its targets the phosphatase CheZ and the flagellar switch protein FliM
TL;DR: Interaction with these three proteins of the signal transduction pathway are mutually exclusive, and it may be that the C-terminal region of CheY is most sensitive for the conformational changes occurring upon phosphorylation.

Involvement of opsins in mammalian sperm thermotaxis.
Serafín Pérez-Cerezales,Sergii Boryshpolets,Oshri Afanzar,Alexander Brandis,Reinat Nevo,Vladimir Kiss,Michael Eisenbach +6 more
TL;DR: It is demonstrated by molecular, immunological, and functional approaches that opsins are present in human and mouse spermatozoa at specific sites, and that they are involved in sperm thermotaxis via two signalling pathways—the phospholipase C and the cyclic-nucleotide pathways.
