Analogs of S-adenosyl-L-methionine (SAM) are increasingly applied to the methyltransferase (MT) catalysed modification of biomolecules including proteins, nucleic acids, and small molecules. However, SAM and its analogs suffer from an inherent instability, and their chemical synthesis is challenged by low yields and difficulties in stereoisomer isolation and inhibition. Here we report the chemo...

In previous studies, Sall et al. (1956) employing resting cells of Corynebacterium diphtheriae, and Mludd et al. (1956, 1958) employing resting cells of Mycobacteria, demonstrated that malate as substrate enhances the accumulation of polyphosphate (metaphosphate) in the form of metachromatic granules and glucose promotes the withdcrawal of polyphosphate. Similarly, AIudd et al. (1958), employin...

1047 ABSTRACT The formation of the proper number of functional nephrons requires a delicate balance between renal progenitor cell self-renewal and differentiation. The molecular factors that regulate the dramatic expansion of the progenitor cell pool and differentiation of these cells into nephron precursor structures (renal vesicles) are not well understood. Here we show that Sall1, a nuclear ...

Background African countries face multiple developmental, economic, social and industrial transformation hurdles, especially in the era of sustainable development sensitivity to environmental damage. As late-comer industrialisers, there is some catching up do, but they need navigate complex, international, legal institutional agreements that early industrialisers did not face. Given concerns, i...

Self-access language learning (SALL) can promote autonomy among learners. It is a practical means for creating comfortable, personalized environments in which learners take more active part making decisions and choices their trajectories. In the domain of second (L2) listening, self-access work fulfill individual needs whose listening processes are supposed to be respected. However, countries w...
