... GH13 enzymes is the lack of domain B protruding out of the TIM barrel in the place of loop 3 connecting the b3-strand to the a3-helix [9,21]. Sharing domain B by rBATs and GH13 enzymes, and especially ... barrel domain, including domain B and the C-terminal domain C for GH13 enzymes (572 residueson average); and (c) the N-terminal region, transmem-brane segment, central TIM barrel domain and the C-terminal ... the b-strandsb2, b3, b4 and b8 of the (b ⁄ a)8barrel domain, and for rBAT also with the short stretch near the C-terminus of domain B [9,19]. From the sequence–structure point of view, the basic...
