Intein_assisted_Bisection_Mapping
Intein_assisted_Bisection_Mapping_collection Version 1 (Collection)
Split inteins are powerful tools for seamless ligation of synthetic split proteins. Yet, their use remains limited because the already intricate split site identification problem is often complicated by the requirement of extein junction sequences. To address this, we augmented a mini-Mu transposon-based screening approach and devised the intein-assisted bisection mapping (IBM) method. IBM robustly revealed clusters of split sites on five proteins, converting them into AND or NAND logic gates. We further showed that the use of inteins expands functional sequence space for splitting a protein. We also demonstrated the utility of our approach over rational inference of split sites from secondary structure alignment of homologous proteins. Furthermore, the intein inserted at an identified site could be engineered by the transposon again to become partially chemically inducible, and to some extent enabled post-translational tuning on host protein function. Our work offers a generalizable and systematic route towards creating split protein-intein fusions and conditional inteins for protein activity control.

SBOLDesigner CAD Tool
SBOLDesigner Version 3.0 (Agent)
SBOLDesigner is a simple, biologist-friendly CAD software tool for creating and manipulating the sequences of genetic constructs using the Synthetic Biology Open Language (SBOL) 2 data model. Throughout the design process, SBOL Visual symbols, a system of schematic glyphs, provide standardized visualizations of individual parts. SBOLDesigner completes a workflow for users of genetic design automation tools. It combines a simple user interface with the power of the SBOL standard and serves as a launchpad for more detailed designs involving simulations and experiments. Some new features in SBOLDesigner are SynBioHub integration, local repositories, importing of parts/sequences from existing files, import and export of GenBank and FASTA files, extended role ontology support, the ability to partially open designs with multiple root ComponentDefinitions, backward compatibility with SBOL 1.1, and versioning.
