Synthesis of beta-alanine (beta-Ala) containing dipeptide using S9 aminopeptidase from Streptomyces thermocyaneoviolaceus NBRC14271 (S9AP-St) was demonstrated with beta-Ala-benzyl ester (-OBzl) and various L-aminoacyl derivatives. For synthesis of beta-Ala-containing dipeptide, beta-Ala-OBzl was used preferentially as the acyl donor for S9AP-St, producing

Dipeptide synthesis by aminopeptidase from Streptomyces septatus TH-2 (SSAP) was demonstrated using free amino acid as an acyl donor and aminoacyl methyl ester as an acyl acceptor in 98% methanol (MeOH). SSAP retained its activity after more than 100 h

E2F1, E2F2, and E2F3A, the three activators of the E2F family of transcription factors, are key regulators of the G1/S transition, promoting transcription of hundreds of genes critical for cell-cycle progression. We found that during late S and in G2

DNA replication errors generate complex chromosomal rearrangements and thereby contribute to tumorigenesis and other human diseases. One mechanism that triggers these errors is mitotic entry before the completion of DNA replication. To address how mitosis might affect DNA replication, we
