Plasmonic Colorimetric Biosensing of Proteins in Biofluids In article number 2101291, Younggeun Park, Xiaogan Liang, Katsuo Kurabayashi, and co-workers demonstrate rapid, “mix-and-read” detection cancer marker proteins at sub-femtomolar concentrations unprocessed whole blood using a multilayered molybdenum disulfide photoconductive channel plasmonic nanoparticles. Minimized carrier scattering w...

A cerulenin insensitive 3-ketoacyl-acyl carrier protein synthase has been assayed in extracts of spinach (Spinacia oleracea) leaf. The enzyme was active in the 40 to 80% ammonium sulfate precipitate of whole leaf homogenates and catalyzed the synthesis of acetoacetyl-acyl carrier protein. This condensation reaction was five-fold faster than acetyl-CoA:acyl carrier protein transacylase, and the ...

Lactococcus lactis is a lactic acid bacterium of proven safety for use in human oral applications. For this purpose, surface display of recombinant proteins is important, and new approaches for it are being sought. Analysis of the bacterial surface proteome is essential in identifying new candidate carrier proteins for surface display. We have made two different predictions of surface-associate...

The expression of dystrophin, the dystrophin-associated proteins and utrophin has been studied immunocytochemically in three young, manifesting carriers of Duchenne muscular dystrophy, aged 3, 5 and 12 yrs, one adult manifesting carrier, aged 60 yrs, and one presumptive carrier with a raised serum creatine kinase, aged 24 yrs, the mother of the 5-yr-old manifesting carrier. The manifesting carr...

Amino acid:[carrier protein] ligases (aa:CP ligases) are newly discovered homologs of aminoacyl-tRNA synthetases (aaRS) which aminoacylate carrier proteins instead of tRNA. Activated amino acids are attached to prosthetic group of carrier proteins by thioester bond. Weak thioacylation activity was observed for many conventional aaRS. Therefore, different thiols were investigated as substrate an...
