Starch Branching Enzymes (SBE) catalyze the formation of α(1 → 6) branching points on starch polymers: amylopectin and amylose. SBEs are classified in two groups named type 1 and 2. Both types are present in the entire plant kingdom except in some species such as Arabidopsis thaliana that expresses two type 2 SBEs: BE2.1 and BE2.2. The present work describes in vitro enzymatic characterization of...
Telomere length is involved in cell survival, tumorigenesis, and early aging. We present here an innovative method to determine the mean telomere length without any DNA purification. Our strategy is to measure both the DNA concentration and the number of telomeric units (TTAGGG) directly from cell lysate produced by the combined action of NaOH (pH>13) and sonication directly on cell pellet. Telomere...
