“…TBM is based upon the observation that many proteins share similar structures even if their sequences diverge ( Kinch and Grishin, 2002 ; Zhang and Skolnick, 2005 ). The quality of TBM critically depends on accurate sequence-template alignment and correct template recognition, both of which are challenging when only distantly-related templates are available for a protein sequence under prediction ( Cozzetto and Tramontano, 2004 ; Hou, et al , 2018 ; Jo, et al , 2015 ; Jones, 1997 ; Peng and Xu, 2011a ; Peng and Xu, 2011b ; Zhu, et al , 2017 ).…”
