| - | Bap1 is a two-domain assembly which is made up of an eight-bladed β-propeller interrupted by a β-prism domain. The β-propeller domain is the larger of the two domains while the β-prism is the smaller of the two. The β-propeller is composed of 8 β-sheets with 3 greek keys present in between β-sheets 5 and 6 of the propeller <ref name="Bap1">PMID:31439670</ref>. It is believed the lectin binding site is in the β-prism domain. | + | Bap1 is a two-domain assembly which is made up of an <scene name='82/823086/Beta_propeller/2'>eight-bladed β-propeller</scene> interrupted by a β-prism domain.

There has not been a catalytic triad found for Bap1, but several amino acids are believed to play a role in the binding of citrate and carbohydrates. There are 6 amino acids believed to bind carbohydrates: Gly-344, Ala-345, Val-346 Asp-348, His-500, and Lys-501 <ref name="Bap1"/>. With the exception of His-500, the other amino acids are structurally the same as the binding site of carbohydrates in RbmC. The amino acids interact with the substrate by either hydrogen bonding or Van der Waals forces. The binding site for citrate and carbohydrates is at the end of the β-prism which has a positively charged, <scene name='82/823086/Lys_in_active_site/1'>lysine-rich central cavity</scene>. | There has not been a catalytic triad found for Bap1, but several amino acids are believed to play a role in the binding of citrate and carbohydrates.
