Karla takes netball world by storm
Karla Pretorius, vice-captain of the Protea netball team, has become a leading player in world netball.

The University of the Free State (UFS) has produced a number of exceptional netball players over the years, but none quite on the level of Karla Pretorius, who is widely considered as probably the very best in her position.

 

A whole new level


Pretorius, who is completing her postgraduate studies in Dietetics, was already deemed one of the best when she left for Australia at the end of 2016; however, she has since risen to a whole new level. The Protea vice-captain plays for the Sunshine Coast Lightning in Australia’s Suncorp Super Netball league, the world’s leading competition. She is scheduled to return there again next year. Karla comfortably leads the stats with a total of 50 intercepts and was named in the Team of the Tournament.

 

According to the former Australian coach, Norma Plummer, who is now at the helm of the Proteas, “Karla currently has to be one of the best, if not the best, goal defenders playing at this moment in time.”

 

Karla’s ability to come through with speed-anticipating interceptions is something that is so exciting to watch. She is very versatile and can switch from one-on-one to split circle or other defensive styles, explained Norma. She says Karla is light in stature but physically very strong.

 

Keep on improving

 

According to Pretorius, who played for the Kovsies between 2009 and 2015, playing in an environment where every possible aspect gets attention – with emphasis on detail – has benefited her immensely. “Everything is done so professionally to eventually push you to become the best possible player.” Karla explained that she experiences challenges in many fields of her life but has the chance to play with and against the best players with different skills, which helps her to keep on improving and bettering her craft.

“Crystallography forms part of everyday life.” This is according to Prof Elspeth Garman, eminent researcher from the Department of Biochemistry, University of Oxford in England, who was hosted by Dr Alice Brink, Department of Chemistry at the University of the Free State (UFS) Bloemfontein Campus. Prof Garman presented a lecture in the Department of Chemistry, titled ‘104 years of crystallography: What has it taught us and where will it lead’. She also taught the postgraduate students how to refine and mount protein structures in cold cryo conditions at about -173°C.

What is Crystallography?
Crystallography is the scientific technique which allows for the position of atoms to be determined in any matter which is crystalline.
 
“You cannot complete Protein Crystallography without the five key steps, namely obtaining a pure protein, growing the crystal, collecting the data, and finally determining the structure and atomic coordinates,” said Prof Garman. Apart from teaching, she was also here to mentor and have discussions with UFS Prestige Scholars on how to face academic challenges in the professional environment.

Discovery of the first crystal structure of a TB protein

Prof Garman successfully determined the first crystal structure of a Tuberculosis protein (TBNAT), a project that took about 15 years of research. In partnership with the Department of Pharmacology at Oxford University and an outstanding PhD student, Areej Abuhammad, they managed to grow only one TBNAT crystal, one-fiftieth of a millimetre. They also managed to solve the structure and publish it.

Dr Alice Brink, Senior Lecturer in the Department of Chemistry, says, “It’s an incredible privilege to have Prof Garman here and to have her share her wisdom and knowledge so freely with the young academics.”
