Laboratory evolution in Novosphingobium aromaticivorans enables rapid catabolism of a model lignin-derived aromatic dimer

M. N. Allemann, R. Kato, W. G. Alexander, R. J. Giannone, N. Kamimura, E. Masai, J. K. Michener

This study uses experimental evolution to identify mutations that enhance catabolism of a lignin-derived aromatic dimer in Novosphingobium aromaticivorans, revealing a key enzyme involved in its degradation.

Stereoinversion via alcohol dehydrogenases enables complete catabolism of β-1-type lignin-derived aromatic isomers

R. Kato, K. Maekawa, S. Kobayashi, S. Hishiyama, R. Katahira, M. Nambo, Y. Higuchi, E. Kuatsjah, G. T. Beckham, N. Kamimura, E. Masai

This paper identifies the catabolic pathway for threo-DGPD in SYK-6, showing it is converted to erythro-DGPD via oxidation and reduction by multiple dehydrogenases, enabling complete catabolism of all four β-1-type lignin-derived isomers.

Functional roles of multiple Ton complex genes in a Sphingobium degrader of lignin-derived aromatic compounds

M. Fujita, S. Yano, K. Shibata, M. Kondo, S. Hishiyama, N. Kamimura, E. Masai

The paper investigates the role of Ton complex genes in the uptake of lignin-derived aromatics in Sphingobium sp. strain SYK-6, showing that the tonB1 operon enhances aromatic conversion.

Sphingobium sp. SYK-6 syringate O-demethylase gene is regulated by DesX, unlike other vanillate and syringate catabolic genes regulated by DesR

T. Araki, K. Tanatani, N. Kamimura, Y. Otsuka, M. Yamaguchi, M. Nakamura, E. Masai

This study identifies DesX as a regulator of desA transcription in Sphingobium sp. SYK-6, unlike DesR which regulates ligM and desB, revealing distinct regulatory mechanisms for syringate and vanillate catabolism.
