autolysis and related proteolysis in swiss cheese for two lactobacillus helveticus strains. | intracellular peptidases of lactobacillus helveticus may play a major role in the proteolysis of swiss cheeses, provided that they are released through bacterial lysis. experimental swiss cheeses were manufactured on a small scale from thermized and microfiltered milk using as starters (in addition to streptococcus thermophilus and propionibacterium freudenreichii) one of two lb. helveticus strains, itglh1 and itglh77, which undergo lysis to different extents in vitro. all the cheeses were bioch ... | 2000 | 10840680 |
structural interpretations of f(0) rotary function in the escherichia coli f(1)f(0) atp synthase. | f(1)f(0) atp synthases are known to synthesize atp by rotary catalysis in the f(1) sector of the enzyme. proton translocation through the f(0) membrane sector is now proposed to drive rotation of an oligomer of c subunits, which in turn drives rotation of subunit gamma in f(1). the primary emphasis of this review will be on recent work from our laboratory on the structural organization of f(0), which proves to be consistent with the concept of a c(12) oligomeric rotor. from the nmr structure of ... | 2000 | 10838053 |
operation of the f(0) motor of the atp synthase. | atp, the universal carrier of cell energy is manufactured from adp and phosphate by the enzyme atp synthase using the energy stored in a transmembrane ion gradient. the two components of the ion gradient (deltaph or deltapna(+)) and the electrical potential difference deltapsi are thermodynamically but not kinetically equivalent. in contrast to accepted wisdom, the electrical component is kinetically indispensable not only for bacterial atp synthases but also for that from chloroplasts. recent b ... | 2000 | 10838052 |
