Software-supported USER cloning strategies for site-directed mutagenesis and DNA assembly
Keywords: : DNA assembly, USER cloning, primer design, site-directed mutagenesis, point mutation, web server.
Input options Site directed mutagenesis - introduce insertions, mismatch mutations and deletions Combinatorial assembly Advanced PCR settings Salt and primer concentrations Specification of primer Tm Output options Linear Circular (default): Into a USER cassette Cassette options Basic: Predefined fusion cassettes Advanced: User designed cassettes Example of input/output data Example 1 Construction of a plasmid from 3 parts INPUT RESULTS PAGE Example 2 A point mutation and addition of a His-tag to GFP in a vector INPUT RESULTS PAGE Example 3 Construction of a small combinatorial vector library INPUT RESULTS PAGE Primer evaluation parameters Restrictions on use
Example - Site directed mutagenesisMultiple sites can be targeted anywhere in a sequence by the introduction of more squared brackets.

Tm of primers: AMUSER ranks the Tm of primers on whether it is in the range 55-72 C. Primers for which the Tm falls in this region are marked with a green "Yes", primers for which the Tm falls outside this region are marked with a red "No".
GC content: The GC content (number of dGTP plus dCTP as a percentage of the total number of nucleic acid residues) should ideally be between 40-60 %, to keep annealing temperature within a favorable range. Primers for which the GC content falls in this region are marked with a green "Yes", primers for which the GC content falls outside this region are marked with a red "No".
Presence of 3' end GC clamp: Due to the stronger annealing of guanine and cytosine with complementary bases, specific binding is promoted by the presence of at least one of either of these bases in the last five bases of the 3' end (GC-clamp). Primers which have 1 or 2 G or C in this region are marked with a green "Yes", primers which have 0 or more than 2 G or C in this region are marked with a red "No".
More than 3 G/C out of last 5 bases at 3' end?: If more than 3 out of the last 5 bases at the 3' end are guanine or cytosine, the binding to the DNA fragment may be too strong. Primers which have less than 3 G or C in this region are marked with a green "No", primers which have 3 or more C in this region are marked with a red "Yes".
Risk of primer dimer formation in primer pair: Stretches of more than five complimentary bases between different primers used in the same PCR can lead to primer dimer formation, which can interfere with the desired hybridization and result in reduced PCR efficiency. With AMUSER the risk of inter-primer homology is assessed based on the relationship between the Tm of the primer and the complimentary bases potentially leading to undesirable dimerization. If the Tm of the potential inter-primer dimerization is at least 10C smaller than that of the annealing temperature used in the PCR cycle, the risk of homology is considered theoretical and the parameter is marked with a green "No", since most of the DNA which could undesirably hybridize is denatured at this higher temperature. If the opposite is the case, the parameter is marked with a red "Yes".
Risk of intra-primer homology (secondary structures): Similarly, stretches of more than three complimentary bases within a primer can lead to formation of intra-primer secondary structures, resulting in reduced PCR efficiency. With AMUSER the risk of intra-primer homology is assessed based on the relationship between the Tm of the primer and the complimentary bases potentially leading to undesirable intra-primer secondary structures. If the Tm of the intra-primer secondary structure formation is at least 10° C smaller than that of the annealing temperature used in the PCR cycle, the risk of homology is considered theoretical and the parameter is marked with a green "No", since most of the DNA which could undesirably hybridize is denatured at this higher temperature. If the opposite is the case, the parameter is marked with a red "Yes".
Presence of PolyN stretches: Sequences consisting of 4 or more consecutive identical nucleotides within the primer are known as polyN stretches; polyG or polyC stretches promote non-specific annealing, whereas polyA or polyT can cause the "opening" of stretches of the primer template complex, referred to as "breathing". If the primers contain stretches of more than 4 consecutive identical nucleotides within a primer, the parameter is highlighted with a red "Yes", if not; the parameter is highlighted with a red "No".
Tm of primers within 2C of each other: For a given primer pair, the primers' Tm should be within 2C of each other, in order to achieve efficient PCR amplification. If this is the case, the parameter is marked with a green "Yes", if not; the parameter is marked with a red "No".

Scientific and Technical problems:
USER cloning is a fast and versatile method for engineering of plasmid DNA. We have developed an easy to use web server tool that automates the design of optimal PCR primers for several distinct USER cloning-based applications. Our web server, named AMUSER (Automated DNA Modifications with USER cloning), facilitates DNA assembly and introduction of virtually any type of site-directed mutagenesis by designing optimal PCR primers for the desired genetic changes. To demonstrate the utility, we designed primers for a simultaneous two-position site-directed mutagenesis of green fluorescent protein (GFP) to yellow fluorescent protein (YFP), which in a single step reaction resulted in a 94% cloning efficiency. AMUSER also supports degenerate nucleotide primers, single insert combinatorial assembly, and flexible parameters for PCR amplification.
