Design Notes
In order to allow for modularity in the promoter region of the cassette, two restriction sites Nde1 (upstream) and BamH1 (downstream) flank it, so that the promoter can be easily excised out and replaced with another and the effect of different promoters on cscB transport efficiency can be studied. Two different restriction sites were chosen in order to allow for directional cloning of the promoter. Thus any promoter that needs to be inserted into this cassette would need to be flanked by Nde1 and BamH1 in order to ligate in a directional manner.
Both ends of the composite part contain Kpn1 restriction sites since this cassette is designed to be cloned into the pSL2680 plasmid which has a Kpn1 site and a Sal1 site to allow for cloning of cassettes. Since this is a linear cassette, in order to cut it using Kpn1, whose recognition sites are at the ends of the cassette, 3 bp sequences were added to allow for efficient cleavage by Kpn1 at the ends.

The terminator (BBa_B0015) is available in the iGEM distribution kit. PcpcB-m6 was generously provided to us by the Wangikar Lab at IIT Bombay. The restriction enzyme sites are incorporated into the cassette by adding them in primers. The homology arms for Neutral Site 1 can be amplified from the S. elongatus UTEX 2973 genome. The cscB gene can be amplified from the pCSCX plasmid, which was a gift from Claudia Vickers (Addgene plasmid # 63918 ; http://n2t.net/addgene:63918 ; RRID:Addgene_63918).
