The reclusive enzymes that catalyze proteolysis inside the cell membrane are among the most widespread in nature, yet most remain ‘orphans’ whose cellular functions are poorly understood. Now, Voss et al identify Golgi-resident glycosyltransferases and glycosidases as substrates for the presenilin-like protease SPPL3. Shedding of these glycan-modifying enzymes from the membrane down-regulates g...

Enzymatic modification results in high-level resistance to aminoglycoside (HLAR), which eliminates the synergistic bactericidal effect of combined exposure to a cell wall-active agent and an aminoglycoside. So aim of the study was to determine prevalence of HLAR enterococcal isolate and to study distribution of aminoglycoside modifying enzyme genes in them. A total of 100 nonrepeat isolates of ...

Fibroblast growth factor (FGF) morphogen signalling through the evolutionarily ancient extracellular signalling-regulated kinase/mitogen activated protein kinase (ERK/MAPK) pathway recurs in many neural and non-neural developmental contexts, and understanding the mechanisms that regulate FGF/ERK function are correspondingly important. The glycosaminoglycan heparan sulphate (HS) binds to FGFs an...

The nuclear pore complex is a multiprotein comprising approximately 30 different proteins called nucleoporins (Nups). Recent studies in yeast, animals, and plants have shown that the Nups bind to chromatin interact with transcription factors, chromatin-remodeling histone-modifying enzymes, structural proteins, including CCCTC-binding factor cohesin. These findings suggest provide subnuclear pla...
