Abstract: A chimeric polypeptide has a first and a second polypeptide chain chemically linked via 1 to 3 cysteine-based disulfide bridges. The first polypeptide chain consists of 1 to 3 cysteines and 4 to 12 basic amino acids preferably selected from the group consisting of arginine, lysine and ornithine. The second polypeptide chain consists of 1 to 3 cysteines and 4 to 12 acidic amino acids selected from the group consisting of glutamate and aspartate. Each polypeptide chain is linked at its C- or N-terminus to a biologically active compound, and is useful as a multimeric pharmaceutical agent.

Abstract: The present invention relates to recombinant DNA which encodes the BpmI restriction endonuclease as well as BpmI methyltransferase, expression of BpmI restriction endonuclease from E. coli cells containing the recombinant DNA. BpmI endonuclease is a fusion of two distinct elements with a possible structural domains of restriction-methylation-specificity (R-M-S). This domain organization is analogous to the type I restriction-modification system with three distinct subunits, restriction, methylation, and specificity (R, M, and S). Because BpmI is quite distinct to other type IIs restriction enzymes, it is proposed that BpmI belongs to a subgroup of type II restriction enzymes called type IIf (f stands for fusion of restriction-modification-specificity domains). The Type IIf group of restriction enzyme includes Eco57I, BpmI, GsuI, BseRI and some other restriction enzymes that cut downstream sequences at long distance, 10-20 bp downstream of recognition sequence, such as MmeI (N20/N18)).

Abstract: The invention discloses a novel thermostable D-hydantoinase, and relates to the nucleic acid sequence, amino acid sequence and vector constructs of the enzyme. The thermostable D-hydantoinase of the invention shows about 45%-70% identity in amino acid sequence with other D-hydantoinases. The thermostable D-hydantoinase of the invention converts 5′-substituted D-hydantoinase to the corresponding N-carbamoyl-D- and/or -L-&agr;/&bgr;-amino acids, and retains at least 50% activity after 30 days at 50° C. In addition, the enzyme activity can also enhanced by certain divalent cations.
