GlutathioneS-transferases (GSTs) catalyze the conjugation of glutathione
to hydrophobic compounds, contributing to the metabolism of toxic
chemicals. In this study, we show that two naturally occurring tau GSTs
(GSTUs) exhibit distinctive kinetic parameters towards 1-chloro-2,4-dini-trobenzene (CDNB), although they differ only in three amino acids
(Arg89, Glu117 and Ile172 in GSTU1 are replaced by Pro89, Lys117 and
Val172 in GSTU2).
Protein misfolding and deposition underlie an increasing number of debili-tating human disorders. Alzheimer’s disease is pathologically characterized
by the presence of numerous insoluble amyloid plaques in the brain, com-posed primarily of the 42 amino acid humanb-amyloid peptide (Ab42).
Disease-linked mutations in Ab42 occur in or near a central hydrophobic
cluster comprising residues 17–21.
Signal peptides that direct protein export inBacillus subtilisare overall
more hydrophobic than signal peptides inEscherichia coli. To study the
importance of signal peptide hydrophobicity for protein export in both
organisms, the a-amylase AmyQ was provided with leucine-rich (high
hydrophobicity) or alanine-rich (low hydrophobicity) signal peptides.
AmyQ export was most efficiently directed by the authentic signal peptide,
both in E. coliand B. subtilis.
Signal sequences often containa-helix-destabilizing amino
acids within the hydrophobic core. In the precursor of the
Escherichia coliouter-membrane protein PhoE,the glycine
residue at position)10 (Gly
) is thought to be responsible
for the break in the a-helix. Previously,we showed that
substitution of Gly
bya-helix-promoting residues (Ala,
Cys or Leu) reduced the proton-motive force dependency of
the translocation of the precursor,but the actual role of the
helix breaker remained obscure. ...
Penicillin acylase of Escherichia coli catalyses the hydrolysis and synthesis of b-lactam antibiotics. To study the role of hydrophobic residues in these reactions, we have mutated three active-site phenylalanines. Mutation of aF146, bF24 and bF57 to Tyr, Trp, Ala or Leu yielded mutants that were still capable of hydrolysing the chromogenic substrate 2-nitro-5-[(phenylacetyl)amino]-benzoic acid. Mutations on positions aF146 and bF24 inﬂuenced both the hydrolytic and acyl transfer activity.
Pyridoxal 5¢-phosphate-dependent enzymes may be grouped into five struc-tural superfamilies of proteins, corresponding to as many fold types. The
fold type I is by far the largest and most investigated group. An important
feature of this fold, which is characterized by the presence of two domains,
appears to be the existence of three clusters of evolutionarily conserved
A structural motif called the small exterior hydrophobic cluster (SEHC)
has been proposed to explain the stabilizing effect mediated by solvent-exposed hydrophobic residues; however, little is known about its biological
roles. Unusually, in D
-3-ketosteroid isomerase from Pseudomonas putida
biotype B (KSI-PI) Trp92 is exposed to solvent on the protein surface,
forming a SEHC with the side-chains of Leu125 and Val127.
Host-guest complexation relies on interactions of molecules through secondary chemical bonds. Such complexation can lead to formation of loose associations, as well as to that of very stable adducts. In formation of these addition compounds, important roles are played by hydrogen-bonding and hydrophobic interactions. In certain cases one of the reacting partners will wind up in a relatively enclosed space, embraced by the other reactant this is when the host-guest description is most appropriate.
Surface water treatment is a controversial issue. A healthy balance between possible risks, such as
immediate microbiological contamination and long-term carcinogenic effects due to dsinfection byproducts,
and the treatment costs is required. Another issue of concern relates to drinking water
standards, whch seem unreasonably strict in some countries and practically absent in others. The price
people are required to pap for their water varies with the standards.
Smart polymers are macromolecules capable of undergoing rapid, reversible
phase transitions from a hydrophilic to a hydrophobic microstructure. These
transitions are triggered by small shifts in the local environment, such as
slight variations in temperature, pH, ionic strength, or the concentration of
specific substances like sugars.
Smart polymers have an extensive range of applications, but this book
focuses solely on their roles within the fields of bioseparation and biomedicine.
Until recently, polymers were considered to be passive participants
within these fields.
