AbstractThe highly active natural product yatakemycin (YTM) from Streptomyces sp. TP-A0356 is a potent DNA damaging agent with antimicrobial and antitumor properties. The YTM biosynthesis gene cluster (ytk) contains several toxin self-resistance genes. Of these, ytkR2 encodes a DNA glycosylase that is important for YTM production and host survival by excising lethal YTM-adenine lesions from the genome, presumably initiating a base excision repair (BER) pathway.

IntroductionUltrasound refers to sound waves with frequencies above 20,000 Hertz (Hz), which exceeds the human hearing range of 20 Hz–20 kHz. With its high frequency and short wavelength, ultrasound has linear propagation capabilities within a finite distance, high beam focusing and excellent directionality features (Dell'Italia et al., 2022). Moreover, ultrasound is a noninvasive technique for neural regulation.
