Presence of an Inducible Semicarbazide-Sensitive Amine Oxidase in Mycobacterium sp. Strain JC1 DSM 3803 Grown on Benzylamine: Young-Tae Ro , Hyun-Il Lee , Young-Min Kim; J. Microbiol. 2006;44(2):243-247.; DOI: https://doi.org/2359 [pii]

Abstract: Mycobacterium sp. strain JC1 was capable of growth on benzylamine as a sole source of carbon and energy. The primary deamination of benzylamine was mediated by an inducible amine oxidase, which can also oxidize tyramine, histamine, and dopamine. Inhibitor study identified this enzyme as a copper-containing amine oxidase sensitive to semicarbazide.

Enzyme Activities Related to the Methanol Oxidation of Mycobacterium sp. strain JC1 DSM 3803: Youngtae Ro , Eungbin Kim , Youngmin Kim; J. Microbiol. 2000;38(4):209-217.

Abstract: Mycobacterium sp. strain JC1 DSM 3803 grown in methanol showed no methanol dehydrogenase or oxidase activities found in most methylotrophic bacteria and yeasts, respectively. Even though the methanol-grown cells exhibited a little methanol-dependent oxidation by cytochrome c-dependent methanol dehydrogenase and alcohol dehydrogenase, they were not the key enzymes responsible for the methanol oxidation of the cells, in that the cells contained no c-type cytochrome and the methanol oxidizing activity from the partially purified alcohol dehydrogenase was too low, respectively. In substrate switching experiments, we found that only a catalase-peroxidase among the three types of catalase found in glucose-grown cells was highly expressed in the methanol-grown cells and that its activity was relatively high during the exponential growth phase in Mycobacterium sp. JC1. Therefore, we propose that catalase-peroxidase is an essential enzyme responsible for the methanol metabolism directly or indirectly in Mycobacterium sp. JC1.

Phylogenetic Analysis of Mycobacterium sp. C2-3 Degrading Polycyclic Aromatic Hydrocarbons: Il-Gyu Lee , Suk-Kyun Han , You-Seak Go , Tae-Young Ahn; J. Microbiol. 2001;39(4):326-330.

Abstract: Mycobacterium sp. C2-3 was isolated from petroleum-contaminated soil around an oil reservoir and identified by analysis of its 16S rRNA gene sequence. Strain C2-3 was able to use fluorene, phenanthrene, fluoranthene and pyrene as sole sources of carbon and energy, yet unable to degrade naphthalene. The strain was also able to use n-alkanes, such as hexadecane and heptadecane, and phenanthrene and pyrene, in particular, were degraded rapidly. The phylogenetic data suggested that the isolate C2-3 is a thermosensitive, fast-growing strain of Mycobacterium sp.
