Seven families of RNA ligases, previously isolated from random RNA sequences,
fall into three classes on the basis of secondary structure and regiospecificity
of ligation. Two of the three classes of ribozymes have been engineered to act as
true enzymes, catalyzing the multiple-turnover transformation of substrates into
products. The most complex of these ribozymes has a minimal catalytic domain of
93 nucleotides. An optimized version of this ribozyme has a kcat exceeding one
per second, a value far greater than that of most natural RNA catalysts and
approaching that of comparable protein enzymes. The fact that such a large and
complex ligase emerged from a very limited sampling of sequence space implies the
existence of a large number of distinct RNA structures of equivalent complexity
and activity.
Here we have research demonstrating the spontaneous formation of vesicles.

Self-assembly is considered one of the driving forces behind abiogenesis and
would have been affected by the environmental conditions of early Earth. The
formation of membranes is a key step in this process, and unlike large dialkyl
membranes of modern cells the first membranes were likely formed from small
single-chain amphiphiles, which are environment-sensitive. Fatty acids and their
derivatives have been previously characterized in this role without concern for
the concentrations of ionic solutes in the suspension. We determined the critical
vesicle concentration (CVC) for three single-chain amphiphiles with increasing
concentrations of NaCl. All amphiphile species had decreasing CVCs correlated to
increasing NaCl concentrations. Decanoic acid and oleic acid were impacted more
strongly than monoacylglycerol, likely because of electric shielding of the
negatively charged headgroups in the presence of salt. There was no impact on the
salt species as 100 mM NaBr, NaCl, and KCl all exhibited the same effect on CVC.
This research shows the importance of salt in both the formation of life and in
experimental design for aggregation experiments.
