Abstract: Bacterial strain NYT501, which we previously isolated from soil, was identified as Stenotrophomonas maltophilia, and it was confirmed that this strain produces an intracellular β-N-acetylhexosaminidase exhibiting transglycosylation activity. Several properties of this enzyme were characterized… read more here.

Abstract: Abstract Monohydroxy heterocyclic aromatic compounds are the widely-used precursors for pharmaceutical synthesis. In this work a whole-cell catalyst was constructed to generate hydroxylated aromatics efficiently using the ring-hydroxylating dioxygenase (RHD) from Sphingobium yanoikuyae SJTF8. With… read more here.
