Nevertheless, in many cases despite extensive geometric data of the manufactured, real workpiece it is not possible to make a clear statement about the functional ability, because conventional concepts of tolerancing are solely geometry-oriented and standardized surface parameters are not sufficient or even missing completely for characterizing the degree of ability to fulfil a function.
The multihaem cytochromes MtrF, OmcA and OmcB may fulfil a function as terminal dye reductase (Brigé et al. 2008).
A non-classical type of arabinogalactan protein is suggested to fulfil a function of intercellular communicator, known as hypothetical xylogen [ 44].

For instance, the anterior intraparietal area (AIP) would be an ideal candidate to fulfil such a function, as it is heavily implicated in the planning and execution of grasping actions [22], [23].
If phosphatase-mediated negative regulation of MAPKs occurs in the parasite as it does in mammalian cells, PF14_052x and PFC0380w are the most likely candidates in the Plasmodium phosphatome to fulfil such a function, in view of their position in the PTP tree; however, this hypothesis remains to be tested experimentally.
Finally, the neofunctionalization (neo-f) model [ 23] postulates that one paralog is recruited to fulfil a new function while the other preserves the ancestral function [ 22].
