Function

[CMOA_ECOLI] Catalyzes the conversion of 5-methoxyuridine (mo5U) to uridine-5-oxyacetic acid (cmo5U) at position 34 in tRNA. May also participate in the methylation of uridine-5-oxyacetic acid (cmo5U) to uridine-5-oxyacetic acid methyl ester (mcmo5U) (By similarity).

About this Structure

4iwn is a 2 chain structure with sequence from Streptomyces aureorectus. Full crystallographic information is available from OCA.
