Figure 3. Proposed mechanism facilitating the relocation of the AOX1 locus as found in clone JPS014.

Figure 3

(A) After transformation the linear GFP expression cassette from pAHBgl-GFP moved to chromosome 4, where the AOX1 locus is situated. (B) Two distal homologous sequences of the cassette with the chromosomal AOX1 locus mediate a double cross-over recombination event (C) The cassette has replaced the AOX1 locus on chromosome 4 (D) The excised linear AOX1 locus moved to chromosome 2 (E) Potentially due to a DSB initiating the NHEJ pathway, the AOX1 locus is integrated into a random gene on chromosome 2 (F) The untargeted gene PP7435_Chr2-1130 was disrupted. While the AOX1 locus is still functional, the disruption of the untargeted gene likely led to the observed abnormal colony morphology in the case of JPS014.
