Sequence and structural alignment. (A) Sequence alignment of CZT07873 (001 A) and 1 kg1 highlighting conserved regions. (B) Structural alignment of CZT07873 (blue) and 1kg1 (gold) reveals conserved folding in C-terminal domain, suggesting shared functional roles in substrate binding. The proteins are color-coded to differentiate between structures, and aligned regions are highlighted to emphasize structural conservation.
