Outline of Final Research Achievements

Microbacterium sp. HM58-2 has been recently isolated, which grows with non-natural compounds, hydrazides, as sole carbon source. Subsequently, hydrazidase, which catalyzes the hydrazide compounds as substrates, has also been determined. This research aimed to seek the native substrates of hydrazidase and ABC transporter in the same operon and their functions. As results, we have successfully determined the x-ray crystal structures of hydrazidase and a transcription factor, IclR, which regulates the gene expressions of the operon. Based on the crystal structures including the hydrazidase complexed with a non-natural substrate, the substructure of potential native compounds for hydrazidase and the transporter were assumed.
