Characterization of the GDP-D-mannose biosynthesis pathway in Coxiella burnetii: the initial steps for GDP-β-D-virenose biosynthesis. [PDF]
Coxiella burnetii, the etiologic agent of human Q fever, is a gram-negative and naturally obligate intracellular bacterium. The O-specific polysaccharide chain (O-PS) of the lipopolysaccharide (LPS) of C. burnetii is considered a heteropolymer of the two

A mutant of phosphomannomutase1 retains full enzymatic activity, but is not activated by IMP: Possible implications for the disease PMM2-CDG. [PDF]
The most frequent disorder of glycosylation, PMM2-CDG, is caused by a deficiency of phosphomannomutase activity. In humans two paralogous enzymes exist, both of them require mannose 1,6-bis-phosphate or glucose 1,6-bis-phosphate as activators, but only ...

The human urine mannose 6-phosphate glycoproteome [PDF]
Glycoproteins containing the mannose 6-phosphate (Man-6-P) modification represent a class of proteins of considerable biomedical importance. They include over sixty different soluble lysosomal hydrolases and accessory proteins, deficiencies of which result in over forty different known human genetic diseases.

The cation‐independent mannose‐6‐phosphate receptor binds to soluble GPI‐linked proteins via mannose‐6‐phosphate [PDF]
The cation‐independent mannose‐6‐phosphate/insulin‐like growth factor II receptor has been observed to bind to soluble forms of glycosyl‐phosphatidylinositol‐linked molecules, one of mammalian origin (rat Thy‐1) and two of protozoan origins. Of the two phosphate groups found on the soluble forms of the protozoan glycosyl‐phosphatidylinositol‐linked ...

Human immunodeficiency virus-1 uses the mannose-6-phosphate receptor to cross the blood-brain barrier. [PDF]
HIV-1 circulates both as free virus and within immune cells, with the level of free virus being predictive of clinical course. Both forms of HIV-1 cross the blood-brain barrier (BBB) and much progress has been made in understanding the mechanisms by ...

Lysosomal Biology and Function: Modern View of Cellular Debris Bin
Lysosomes are the main proteolytic compartments of mammalian cells comprising of a battery of hydrolases. Lysosomes dispose and recycle extracellular or intracellular macromolecules by fusing with endosomes or autophagosomes through specific waste ...
