11. Streptococcal protein Rib and related proteins: a family of repetitive surface proteins that elicit protective immunity
Abstract : ABSTRACT Streptococci constitute a heterogeneous group of Gram-positive bacteria, divided into different serological groups on the basis of antigenic differences in a cell wall-associated carbohydrate. This thesis describes related surface proteins expressed by bacteria in two of these groups, the group B streptococcus (GBS) and the group A streptococcus (GAS). READ MORE

12. Fighting isoaspartate
Abstract : Isoaspartate (IsoAsp) is a damaging amino acid residue generated either from asparagine (Asn) deamidation or aspartate (Asp) isomerization. Both reactions are spontaneous in physiological conditions and require no enzymes. In isoAsp, a CH2 group is rearranged from the side chain and extends the polypeptide backbone. READ MORE

13. Design and synthesis of -turn peptidomimetics : Applications to angiotensin II
Abstract : This study addresses the issue of how to convert peptides into drug-like non-peptides while retaining the biological activity at peptide receptors. Angiotensin II (Asp-Arg-Val-Tyr-Ile-His-Pro-Phe, Ang II) was used as a model peptide. Small bioactive peptides are in most cases conformationally flexible molecules. READ MORE

14. Regulation of tartrate-resistant purple acid phosphatase by proteolytic processing in rat
Abstract : Purple acid phosphatase (PAP) is an iron-containing binuclear acid metallohydrolase with a characteristic purple colour, also referred to as tartrate-resistant acid phosphatase (TRAP), uteroferrin or type 5 acid phosphatase. PAP is highly expressed in osteoclasts and has a role in bone resorption. READ MORE

15. Expression of Manganese Lipoxygenase and Site-Directed Mutagenesis of Catalytically Important Amino Acids : Studies on Fatty Acid Dioxygenases
Abstract : Polyunsaturated fatty acids can be bioactivated by two families of dioxygenases, which either contain non-heme iron (lipoxygenases) or heme (cyclooxygenases, linoleate diol synthases and α-dioxygenases).Lipoxygenases and their products play important roles in the pathophysiology of plants and fungi.
