TL;DR: The reaction steps proposed for the acyl shift are driven entirely by protonation and deprotonation, in which proton ingress and egress is balanced within the splicing site.
Journal ArticleDOI
Protein splicing: its discovery and structural insight into novel chemical mechanisms.
TL;DR: In this paper, a self-catalytic mechanism for protein splicing that is triggered and terminated solely via thiazolidine intermediates with tetrahedral configurations formed within the splicing sites where proton ingress and egress are driven by balanced protonation and deprotonation is presented.
Journal ArticleDOI
X-ray, kinetics and DFT studies of photochromic substituted benzothiazolinic spiropyrans.
TL;DR: For this class of compounds, both X-ray geometry and DFT optimized geometry may be used to predict photochromism, but not degree of photocolorability.

TL;DR: In this article, a new class of amphiphilic spiropyran derivatives has been designed and synthesized, and their photophysical and photochromic properties have been investigated.
Journal ArticleDOI
Novel synthesis and characterisation of 3,3-dimethyl-5′-(2-benzothiazolyl)-spironaphth(indoline-2,3′-[3H]naphth[2,1-b] [1,4]oxazine) derivatives
TL;DR: In this article, modified spirooxazines (SOs) with additional chelating groups were synthesized and the crystal structure of one of these was determined, showing that the photochromic behavior is altered with Zn 2+ coordination.
