Identification of a functional site on the type I TGF-beta receptor by mutational analysis of its ectodomain.

abstract：:The white-rot fungus Bjerkandera sp. BOS55 produced de-novo several aromatic metabolites. Besides veratryl alcohol and veratraldehyde, compounds which are known to be involved in the ligninolytic system of several other white-rot fungi, other metabolites were formed. These included anisaldehyde, 3-chloro-anisaldehyde ...

abstract：:The AMP-activated protein kinase (AMPK) is the central component of a protein kinase cascade that plays a major role in energy sensing. AMPK is activated pharmacologically by 5-amino-4-imidazolecarboxamide (AICA) riboside monophosphate (ZMP), which mimics the effects of AMP on the AMPK cascade. Here we show that uptak...
