Sequence toolbox for construct design: 1-letter to 3-letter code conversion, codon table, reverse translation optimized for E. coli and for human codon usage, signal-peptide check, simple domain search, and restriction-enzyme sites found in the reverse-translated DNA. Use when going from a protein sequence to an expression construct.

Parameters:
  sequence: Protein amino acid sequence.

Returns: {length, one_to_three, codon_table, reverse_translate_ecoli, reverse_translate_human, signal_peptide_check, domain_search, restriction_sites_in_dna}
