(A) The vertical gene transfer of a toxin-antitoxin system. (B) Horizontal gene transfer of a toxin-antitoxin system. PSK stands for post-segregational killing and TA represents a locus encoding a toxin and an antitoxin.
The hok/sok system is a postsegregational killing mechanism employed by the R1 plasmid in Escherichia coli.It was the first type I toxin-antitoxin pair to be identified through characterisation of a plasmid-stabilising locus. [1]
The "total pages" column refers to the number of pages in all namespaces, including both book modules and non-book modules (user pages, files, talk pages, "project" pages, categories, redirects, and templates).
PDFtk (short for PDF Toolkit) is a toolkit for manipulating Portable Document Format (PDF) documents. [ 3 ] [ 4 ] It runs on Linux , Windows and macOS . [ 5 ] It comes in three versions: PDFtk Server ( open-source command-line tool ), PDFtk Free ( freeware ) and PDFtk Pro ( proprietary paid ). [ 2 ]
Twig Science is a phenomena-based science program for TK/Pre-K to grade 6, built for the Next Generation Science Standards (NGSS) and aimed at California. [8] When developing this product, Twig partnered with SCALE (The Stanford Center for Assessment, Learning, and Equity) to develop the assessments that are embedded throughout the program. [12]
tk_dialog – creates a modal dialog and waits for a response. tk_getOpenFile – pops up a dialog box for the user to select a file to open. tk_getSaveFile – pops up a dialog box for the user to select a file to save. tk_messageBox – pops up a message window and waits for a user response. tk_popup – posts a popup menu.
26S protease regulatory subunit S10B, also known as 26S proteasome AAA-ATPase subunit Rpt4, is an enzyme that in humans is encoded by the PSMC6 gene. [5] [6] [7] This protein is one of the 19 essential subunits of a complete assembled 19S proteasome complex [8] Six 26S proteasome AAA-ATPase subunits (Rpt1, Rpt2, Rpt3, Rpt4 (this protein), Rpt5, and Rpt6) together with four non-ATPase subunits ...
