TABLE 1.

Sequence comparison in percentage identity/percentage similarity among putative αKG:UMP dioxygenases

^a LipL is encoded within the biosynthetic gene cluster for A-90289, Cpz15 within the cluster for caprazamycin, LpmM within the cluster for liposidomycin, Mur16 within the cluster for muraymycin, SphE within the cluster for sphaerimicin, Mra24 within the cluster for muraminomicin, ORF7 within the cluster for A-500359, CapA within the cluster for A-503083, and Cpr19 within the cluster for A-102395.

^b Mra24 appears truncated and inactive, missing 57 amino acids at the C terminus when aligned with LipL.

^c GlyU, 5′-C-glycyluridine-containing nucleoside antibiotics.

^d CarU, uridine-5′-carboxamide-containing nucleoside antibiotics.
