Very recently, glutathione (GSH), either generated by bacteria or derived from host cells, was found to be the essential small molecule cofactor of PrfA through allosteric binding to the protein (Reniere et al., 2015).
Vitamins are essential small compounds to maintain normal activities.
The TSC heterodimer (TSC1-TSC2) is a GTPase activating protein (GAP) that inhibits the essential small GTPase Rheb [25], [26].
However, almost all of the essential small RNAs (sRNAs) are found missing in the original RefSeq annotation.
Glutathione (GSH) is an essential small peptide present throughout the cell that has vital protective roles within mitochondria [4,5].
None of the families shows abnormalities concerning number of members or presence/absence of essential small GTPases.
The spliceosome contains five essential small nuclear RNAs (snRNAs)—U1, U2, U4, U5, and U6 that are essential components for assembling the spliceosome and accomplishing the intricate task of intron removal from newly synthesised eukaryotic RNAs [ 17, 18, 27].
The possible depletion of nutrients (others than glucose and glutamine) as well as the exhaustion of essential small molecules, namely growth factors, not replenished in the glucose fed-batch strategy, may have contributed to arrest cell growth.
In the yeast Saccharomyces cerevisiae, the essential small ubiquitin-like modifier (SUMO) protease Ulp1 is responsible for both removing SUMO/Smt3 from specific target proteins and for processing precursor SUMO into its conjugation-competent form.
