TL;DR: Different approaches led to the joint conclusion that these unicellular Eukarya use the salt-out strategy to cope successfully with the persistent high salinity in their habitat.

TL;DR: The yqiHIK gene cluster from Bacillus subtilis is predicted to encode an extracellular lipoprotein, a secreted N-acetylmuramoyl-L-alanine amidase, and a cytoplasmic glycerophosphodiester phosphodiesterase, but reverse transcriptase PCR analysis showed that the genes are transcribed as an operon.

TL;DR: It is found that (Pl)EctA forms a homodimer whose enzyme activity is highly regiospecific by producing N-γ-ADABA but not the ectoine catabolic intermediate N-α-acetyl-l-2,4-diaminobutyric acid.

TL;DR: The combined biochemical and structural results indicate that the EutD homodimer opens the pyrimidine ring of ectoine through an unusual covalent intermediate, N-α-2 acetyl-l-2,4-diaminobutyrate (α-ADABA), which is found to induce the MocR/GabR-type repressor EnuR, which controls the expression of many ectoine catabolic genes clusters.

TL;DR: A microseeding protocol is devised leading to crystals of ChoX with bound acetylcholine within 24 hours, with one drawback the high twinning fraction of the crystals, possibly was due to the rapid crystal growth.
