The location of the active site is at this amino acid<ref name="Redinbo" />. Residues 636 to 712 form the <scene name='78/781215/04_27_structure_linker/1'>Linker domain</scene> and they contribute to the enzyme catalytic activity but are not required<ref name="Redinbo" />. The core is divided into 3 subdomains: <scene name='78/781215/04_27_structure_core_sd1/1'>Core Sudomain 1</scene>[215-232 & 320-433], <scene name='78/781215/04_27_structure_core_sd2/1'>Core Subdomain 2</scene>[233-319], and <scene name='78/781215/04_27_structure_core_sd3/1'>Core Subdomain 3</scene>[434-635]<ref name="Redinbo"/>. The <scene name='78/781215/04_27_structure_core_cooh/1'>core and the COOH-terminal domains</scene> are very important for the catalytic activity<ref name="Redinbo" />.''' | ||
