A high concentration of potassium phosphate (75--100 mM) stabilized pH and supported extensive growth of Streptomyces clavuligerus in a chemically defined medium; such a concentration also inhibited cephalosporin production. Although Tris buffer was found to have detrimental effects on growth

The endoplasmic reticulum (ER) and mitochondria accumulate Ca(2+) within their lumens to regulate numerous cell functions. However, determining the dynamics of intraorganellar Ca(2+) has proven to be difficult. Here we describe a family of genetically encoded Ca(2+) indicators, named calcium-measuring

Phosphoinositide signaling regulates diverse cellular functions. Phosphoinositide-3 kinase (PI3K) generates PtdIns(3,4,5)P3 and PtdIns(3,4)P2, leading to the activation of proliferative and anti-apoptotic signaling pathways. Termination of phosphoinositide signaling requires hydrolysis of inositol ring phosphate groups through the actions of PtdIns(3,4,5)P3 3-phosphatase
