... catalyst. Identification of flavin cofactor in PRODH Following release from the enzyme, the chemical identity of the flavin cofactor in PRODH was determined by MALDI- TOF MS. Cofactor was released from the enzyme by ... the K + adduct of released FAD cofactor. The m ⁄ z peaks of 348 and 458 represent the [M +H] + ion of both AMP and FMN, respectively, which result from partial hydr...

... [66]. The bookmarking function of HSF2 is achieved by recruitment of protein phos- phatase 2A to inhibit nearby condesin complexes by dephosphorylation. The bookmarking of the HSP70 promoter and other ... bound by HSFs. Efficient trimerization of HSFs is important to establish interactions with the gap- and step-type HSEs. The different types of HSEs result in the induction, b...
