Loop F-Beta

This part is a Loop Type IIS Golden Gate adapter that contains a BsaI and a SapI restriction sites.

Usage and Biology

Figure 1. BsaI and SapI restriction sites (adapted from [1])

The Loop Type IIS cloning sites (triangles in figure 1) are a combination of BsaI and SapI restriction sites each with different cutting sites that generate well defined overhangs (circles in Figure 1 and 2).

A total of 50 combinations are theoretically possible and this part is one of them: the loop F-Beta (Figure 2).

Red triangle: BsaI fixation site (GGTCTC)

Blue circle: overhang formed by SapI after cutting (GCA)

This part was used to define the Loop assembly system dedicated to the oleaginous yeast Yarrowia lipolytica (for details visit https://2019.igem.org/Team:Evry_Paris-Saclay/Design).
