Abstract

Odour detection thresholds, that we have previously obtained, have been analysed by a general equation for selective transport. It is shown that such selective transport can account for some 77% of the total effect. The remainder is due to a specific size effect, that might involve odour-binding proteins, and a specific effect for aldehydes and carboxylic acids. Our analysis raises the question of whether selective transport is physically separable from the specific effects of receptor activation. The model predicts a chemical cut-off in odour detection along any homologous series.

Identification of N epsilon-(carboxyethyl)lysine, one of the methylglyoxal-derived AGE structures, in glucose-modified protein: mechanism for protein modification by reactive aldehydes.

We have developed a separation system for N(epsilon)-(carboxyethyl)lysine (CEL) and N(epsilon)-(carboxymethyl)lysine (CML) by HPLC equipped with a styrene-divinylbenzene copolymer resin coupled with sulfonic group cation-exchange column and examined whether CEL is formed from proteins modified by glucose via the Maillard reaction. CEL was generated by incubating bovine serum albumin (BSA) with glucose, a reaction inhibited by aminoguanidine, but enhanced by phosphate. Although several aldehydes were detected during incubation of N(alpha)-acetyllysine with glucose, incubation of BSA with methylglyoxal alone generated CEL. These results indicate that methylglyoxal is responsible for CEL formation on protein in vitro.

Directed evolution of N-acetylneuraminic acid aldolase to catalyze enantiomeric aldol reactions.

Expanding the scope of substrate specificity and stereoselectivity is of current interest in enzyme catalysis. Using error-prone PCR for in vitro directed evolution, the Neu5Ac aldolase from Escherichia coli has been altered to improve its catalytic activity toward enantiomeric substrates including N-acetyl-L-mannosamine and L-arabinose to produce L-sialic acid and L-KDO, the mirror-image sugars of the corresponding naturally occurring D-sugars. The first generation variant containing two mutations (Tyr98His and Phe115Leu) outside the (alpha,beta)(8)-barrel active site exhibits an inversion of enantioselectivity toward KDO and the second generation variant contains an additional amino acid change Val251Ile outside the alpha,beta-barrel active site that improves the enantiomeric formation of L-sialic acid and L-KDO. The X-ray structure of the triple mutant epNanA.2.5 at 2.3A resolution showed no significant difference between the wild-type and the mutant enzymes. We probed the potential structural 'hot spot' of enantioselectivity with saturation mutagenesis at Val251, the mutated residue most proximal to the Schiff base forming Lys165. The selected variant had an increase in k(cat) via replacement with another hydrophobic residue, leucine. Further sampling of a larger sequence space with error-prone PCR selected a third generation variant with significant improvement in L-KDO catalysis and a complete reversal of enantioselectivity.

The effect of an aldehyde biocide on the performance and characteristics of laboratory-scale rotating biological contactors.

The effect of an aldehyde biocide, glutaraldehyde, on the treatment efficiency of laboratory-scale rotating biological contactors (RBCs) as well as their component biofilms was studied. Biofilms were established on the RBCs and then exposed to 0-120 ppm glutaraldehyde at a flow rate of 2.5 l x h(-1). The results showed that glutaraldehyde up to 80 ppm did not cause any adverse effect on chemical oxygen demand (COD) removal of the RBC units, microbial activity (ATP content) of biofilms on the RBC disc and viability of the biofilms. Glutaraldehyde at 80 ppm could be almost totally removed by the units regardless of the presence of simple carbon sources. There was at least a fourfold difference in susceptibility of planktonic and sessile bacteria to glutaraldehyde. Cells acclimatized to glutaraldehyde did not increase their capability to degrade normal carbon sources or glutaraldehyde under the conditions used in this study.
