Photosystem II photochemistry and phycobiliprotein (PBP) genes of red algae Kappaphycus alvarezii, raw material of κ -carrageenan used in food and pharmaceutical industries, were analyzed in this study. Minimum saturating irradiance (I k) of this algal species was less than 115 μmol m(-2) s(-1). Its actual PSII efficiency (yield II) increased when light intensity enhanced and decreased when lig...

Platelet basic protein (PBP) (isoelectric point, 10.0-10.5; apparent Mr, 11,000-15,000) has been purified to homogeneity from material secreted by fresh human platelets after stimulation by thrombin. The purification, using preparative isoelectric focusing and chromatography on heparin-Sepharose, yielded two additional peptides with antiheparin activity that were immunologically identical with ...

Penicillin-binding protein (PBP) 7 of Escherichia coli is a poorly characterized member of the family of enzymes that synthesize and modify the bacterial cell wall. The approximate chromosomal position of the gene encoding this protein was determined by measuring the expression of PBPs during lytic infection of E. coli by each of the 476 miniset members of the Kohara lambda phage genomic librar...

Penicillin-binding proteins (PBPs), although characterized from several organisms, have so far not been studied in mycobacteria. The present study is the first characterization of a PBP from Mycobacterium smegmatis. The PBP was purified by solubilization of the membranes with Triton X-100 and successive chromatography of the solubilized proteins on ampicillin-linked CH Sepharose 4B and DE-52. T...

An actin-like protein was purified to apparent homogeneity from chick-embryo homogenates and chick-embryo fibroblasts by the use of poly-L-proline-agarose affinity chromatography; we therefore refer to this protein as PBP (poly-L-proline-binding protein). PBP binds to deoxyribonuclease-agarose, co-migrates with known actin standards on SDS/polyacrylamide-gel electrophoresis, and has an amino ac...

While there is broad agreement that the way that health care providers are paid affects their performance, the empirical literature on the impacts of provider payment reforms is surprisingly thin. During the 1990s and early 2000s, many European and Central Asian (ECA) countries shifted from paying hospitals through historical budgets to fee-for-service (FFS) or patient-based payment (PBP) metho...

BACKGROUND Dairy products are important in a healthy diet due to their high nutritional value; they are, however, associated with relatively large greenhouse gas emissions (GHGE) per kg product. When discussing the need to reduce the GHGE caused by the food system, it is crucial to consider the nutritional value of alternative food choices. OBJECTIVE The objective of this study was to elucida...
