You can import custom codon usage tables in GCG CodonFrequency and EMBOSS cusp formats. Lets you select a CUT for the target expression host. You can select a genetic code other than the one that is shown as the default for the selected input documents if you want to override the default. If you have selected multiple source sequence documents with different genetic codes, the choice “Multiple Values” will be available to indicate that the genetic code associated with each document should be used. Lets you select the genetic code to be used when translating the source sequence/s. If you manually select a region, you must ensure the selection is in-frame with the coding sequence. If you wish to optimize a portion of a sequence, for example a CDS annotated as part of a larger sequence, then select the CDS annotation prior to running ): Optimize Selected Region or Full Sequence:įull sequence to optimize the full length sequence. You can configure the following options: (Figure 14.8 In Geneious Prime 2020 and onwards, optimized codons are selected in proportion to their relative frequencies among synonymous codons (i.e., fraction entries in the chosen CUT). Relative adaptiveness is calculated based on the selected CUT. This tool calculates the Codon Adaptation Index (CAI) of a gene sequence as the geometric mean of the relative adaptiveness (w) of the codons in the sequence, as defined in Sharp and Li, 1987. In general, “whole genome” CUTs are biased towards codons used by poorly expressed proteins and will be less likely to yield a CDS that will give optimal high-level expression. In most cases you should not use CUTs compiled from whole genome data, such as those obtained from. We recommend users consult the literature for advice on appropriate CUTs to use for a particular expression host. Geneious Prime provides a number of CUTs you can use, or you can import and use your own custom CUT, see How do I create a custom codon usage table?. “Preferred” codons are specified using an appropriate codon usage table (CUT) that reflects synonymous codon frequencies for coding sequences known (or predicted) to express at high levels in the expression host. Simultaneous sequence optimization while avoiding including or introducing forbidden motifs uses the algorithm described by Condon and Thachuk 2012. In addition, the tool can introduce synonymous codon changes to eliminate “forbidden” sequence motifs, such as homopolymers, recognition sites for a specific set of restriction enzymes, or other undesirable sequences. The resulting sequence is optimized to avoid or reduce the use of codons that rarely occur in the highly expressed genes of the expression host, increasing the likelihood that the gene product will be expressed at a higher level if the optimized sequence is synthesized and recombinantly expressed in the expression host. This tool allows you to adapt a nucleotide sequence to the genetic code and “preferred” synonymous codon usage of a particular expression host.
