Considering the fundamental roles of histone modifications, it is not surprising that aberrations in histone modifications are discovered in cancer.
This is exemplified by methylation, which occurs on numerous lysine and arginine residues in histones and has been intensely studied since enzymes that catalyse these modifications were discovered.
Non-TOMM NHLPs lacking Cys in the core peptide will presumably remain at the dehydrated state, unless new tailoring modifications are discovered that further process these groups.
Over time, as new tRNA modifications were discovered, several cases were found in which the original wobble rules failed to describe the true codon reading Agris (1991); Agris et al., (2007); Guthrie and Abelson (1982); Yokoyama and Nishimura (1995).
A novel DNA modification system was discovered recently in the Gram-positive bacterium Streptomyces lividans 66 [ 31].
Although O-GlcNAc modification of proteins was discovered over two decades ago (Torres and Hart, 1984), little is known about the functions of O-GlcNAc in neuronal cell biology, and roles for O-GlcNAc in primary neurons have not been examined.
A novel chemical modification agent, p-xylenediamine/water, was discovered and shows effectiveness to improve P84 membrane stability for SLM.
Most recently, a novel posttranslational modification of histones, biotinylation, was discovered by one of the co-authors [6], [12], [13] and independently confirmed in another laboratory [14].
Further, another pyroglutamate modification at aspartate 11 was discovered (11pE-Aβ) [ 41, 62].
A novel series of imidazolidinone-based matrix metalloproteinase (MMP) inhibitors was discovered by structural modification of pyrrolidinone 1a.
