    • The present invention concerns the non-random assembling of DNA molecules in a DNA construct and methods of using such constructs, including the production of nucleic acid libraries. The non-random gene shuffling is preferably accomplished by the following steps. First, optionally, the amino acid sequences of proteins encoded by related gene families of interest are aligned and inspected for regions of conserved amino acid residues. These conserved regions, preferably of at least 4 (e.g. about 4 to 10) consecutive conserved amino acid residues are candidate regions for the subsequent design of PCR primers to amplify the variable or less conserved regions in between them, followed by non-random reassembly to create a recombinant nucleic acid genetic library of gene family variants.

    • The instant invention is drawn to the methods and compositions necessary to provide recombinant proteins with a substantially reduced or eliminated content of norleucine or other non-standard amino acids. Various embodiments of the invention provide for the substantial elimination of the incorporation of non-standard amino acids into recombinant proteins by the co-expression or enhanced expression of a protein (or the enzymatically active portion thereof) capable of degrading norleucine or other non-standard amino acids, including norvaline, beta-methylnorleucine, and homoisoleucine. In certain particular embodiments of the invention, the norleucine is degraded by a glutamate dehydrogenase, a leucine dehydrogenase, a valine dehydrogenase, a phenylalanine dehydrogenase, a glutamate/leucine/phenylalanine/valine dehydrogenase, or an opine dehydrogenase. Also provided are the cells and DNA constructs for carrying out these methods.

    • Peptides having four to six amino acid residues are disclosed that possess biological activity. These peptides constitute short fragments of the peptide HB-107 (MPKEKVFLKIEKMGRNIRN), which itself is a fragment of the antimicrobial protein cecropin B, and exhibit cell stimulatory and migratory properties. The inventive peptides comprise four to six contiguous amino acid residues located between position 11 and 16 of HB107 (MPKEKVFLKIEKMGRNIRN), namely EKMGRN. The disclosed peptides comprise a useful agent for the medical treatment of injury to the skin, such as from diabetic ulcers. The peptides also are effective in preventing and reversing skin surface damage resulting from various environmental insults. Importantly, the therapeutic effects of the peptides manifest at concentrations equal to or greater than those of peptide HB-107, and thus represent a less expensive, more versatile means for developing effective therapies. Methods for the production and use of these peptides are also disclosed.
