Table 3. The bioconversion features of pyridine and pyrazine derivatives for which reactions products were detectable.

Substrate		Product
Name	[M+H]+	[M+H]+	NMR	Name/Possible outcome
Pyridine	80	96	−	Hydroxylated at the 1-position
2-Methylpyridine	94	110	−	Hydroxylated at the 1-position
3-Methylpyridine	94	110	−	Hydroxylated at the 1-position
4-Methylpyridine	94	110	−	Hydroxylated at the 1-position
Pyrazine	81	97 and 113	+	pyrazine-1-oxide and pyrazine-1,4-dioxide

For the NMR analysis approximately 10 mg of purified bioconversion product was used.
