O fausaga tioata o carboxypeptidase T (CpT) faʻalavelave faʻatasi ma phenylalanine ma arginine substrate analogs - benzylsuccinic acid ma (2-guanidinoethylmercapto) succinic acid - na fuafuaina e le mole mole suitulaga i iugafono o le 1.57 Å ma le 1.62 Å e faʻamalamalamaina ai le faʻamatalaga lautele lautele. o le enzyme.O toega Leu211 ma le Leu254 faʻasao (o loʻo i ai i le carboxypeptidase A ma le carboxypeptidase B) na faʻaalia e avea ma faʻatonuga faʻavae mo le faʻamaoniaina o mea e faʻaogaina ai le hydrophobic, ae o le Asp263 mo le faʻamaoniaina o mea faʻapipiʻi lelei.O suiga o nei mea e fa'atatauina e suia ai le fa'ailoga o le substrate: o le CpT variant Leu211Gln maua carboxypeptidase B-pei o meatotino, ma le CpT variant Asp263Asn le carboxypeptidase A-like selectivity.O le Pro248-Asp258 matasele fegalegaleai ma Leu254 ma Tyr255 na faʻaalia e nafa ma le amanaʻiaina o le vaega C-terminal toega.O le fusifusia o le eleele i le S1 'lalo e tau atu i le suiga o le ligand-dep endent o lenei matasele, ma le Leu254 itu o filifili filifili e faaosofia ai le toe fetuunaiga o le Glu277 toega taua mo le catalysis.O se fa'amatalaga fou lea i le filifilia o le substrate o metallocarboxypeptidases o lo'o fa'aalia ai le taua o fegalegaleaiga i le va o le S1 'subsite ma le nofoaga autu.
