Biochem/physiol Actions

InsS6 has a molecular footprint and negative surface charge that is similar to that of phytic acid (InsP6), but with lower biological activity. It is used as a control in studies of the cellular actions of phytic acid. It is also a competitive inhibitor of Aspergillus phytase.

Acidic fibroblast growth factor (aFGF) is unstable at physiological temperatures in the absence of polyanions such as heparin. Therefore, the effect of temperature on the kinetics of refolding of aFGF has been examined in the presence and absence of several

The phyA gene from Aspergillus ficuum that codes for a 441-amino-acid full-length phosphomonoesterase (phytase) was cloned and expressed in Medicago sativa (alfalfa) leaves. The expressed enzyme from alfalfa leaves was purified to homogeneity and biochemically characterized, and its catalytic properties

Phytases hydrolyse the phosphomonoesters of phytate (myo-inositol-1,2,3,4,5,6-hexakis phosphate) and thus find uses in plant and animal production through the mobilisation of phosphorus from this source. The structure of partially deglycosylated Aspergillus niger PhyA is presented in apo form and in

The monosaccharide substances inositol hexasulfate (IHS) and inositol hexaphosphoric acid (Phytic acid, IHP) were investigated for their antiviral effect on the human immunodeficiency virus (HIV) in vitro. In MT-4 cells IHS completely inhibited the cytopathic effect of HIV and the

Previous biophysical investigations, including those from our laboratories, have reported that polyphosphates weaken RBC membrane skeletal protein-protein interactions and decrease hemoglobin affinity for oxygen. We have additionally demonstrated that low-affinity intact RBC's may be produced by inositol hexaphosphate (IHP) incorporation
