A new type of enzyme hydrolyzing the elastase substrate succinyl-L-alanyl-L-alanine-4-nitroanilide has been found in cell-free rheuma todi synovial fluid. Normal plasma and osteoarthritic synovial fluid contained relatively little enzyme. The pH optimum was 8.0. Unexpectedly, the enzyme activity was not

The olfactory system of fish comprises several classes of olfactory sensory neurons (OSNs). The odourants L-alanine and taurocholic acid (TCA) specifically activate microvillous or ciliated OSNs, respectively, in fish. We recorded electro-olfactograms (EOG) in fathead minnows (Pimephales promelas; a laboratory-reared

Proteins have nonspecific adsorption capacities for solid surfaces. Although the nonspecific adsorption capacities are generally understood to be related to the hydrophobicity or charge density of the surfaces, little is known at the amino acid level about the interaction between

The cytoplasmic membrane is probably the most important physical barrier between microbes and the surrounding habitat. Aminoacylation of the polar head group of the phospholipid phosphatidylglycerol (PG) catalyzed by Ala-tRNA(Ala)-dependent alanyl-phosphatidylglycerol synthase (A-PGS) or by Lys-tRNA(Lys)-dependent lysyl-phosphatidylglycerol synthase (L-PGS) enables
