“…Typically, the non-enzymatic carbohydrate binding module of a CBM binds to insoluble polysaccharides, and thereby increases their effective concentration near the co-associated enzymatic domain, and enhances catalytic efficiency (Abbott et al 2008;Hoffmam et al 2016). This "proximity effect" is related to the observation that CBMs can increase enzyme processivity (Zheng and Ding 2013).…”

“…This site also includes the hydrophobic Pro390, Pro396, and Leu478 (Figure 5B). In analogy with CBMs, this aromatic/hydrophobic site of the middle domain of KP32gp38 likely plays the role of anchoring the substrate in a cleft close to the catalytic sites to facilitate the strong binding of the appended catalytic modules to their substrates and pro-mote catalysis (Abbott and van Bueren, 2014;Hoffmam et al, 2016;Pires et al, 2004).…”

“…The KP32gp38 modular features likely account for the complex architecture of CPS from K. pneumoniae, which may restrict the accessibility to enzymatic degradation by the catalytic domain. From this perspective, CBM domains typically improve enzymatic degradation by bringing the adjacent catalytic domains into intimate contact with their target substrate (Abbott and van Bueren, 2014;Baroroh et al, 2017;Hoffmam et al, 2016;Kari et al, 2018;Montanier et al, 2009;Pires et al, 2004;Walker et al, 2015). In addition, the H-type lectin domain is endowed with two particular characteristics: it displays carbohydrate binding properties to recognize and efficiently bind to K. pneumoniae CPS and provides a trimerization interface, because KP32gp38 does not contain the C-terminal chaperone securing the protein trimerization as in some other tailspikes (Weigele et al, 2003;Schulz and Ficner, 2011).…”

“…A partir dele, foi possível identificar algumas importantes regiões conservadas e predizer os dois possíveis resíduos catalíticos da Af-XYLA -E150 e E257. Xilanases pertencentes às famílias GH10 e GH11 catalisam a hidrólise das ligações glicosídicas através de um mecanismo de retenção envolvendo dois resíduos de glutamato: um deles que atua como nucleófilo e o outro que age ora como ácido, ora como base (HOFFMAM et al, 2016;SEGATO et al, 2014).…”
