Biomechanics Of Mantis Prey Capture, Danielle S. Taylor
Biomechanics Of Mantis Prey Capture, Danielle S. Taylor
Honors Theses
Mantis species have a variety of different morphologies, so do the extreme forms of mantis limbs trade prey catching capability for camouflage? We hypothesize that some extreme forms of mantis limbs that are associated with cryptic species may be associated with a tradeoff of the capability of those limbs. Previous research has developed 2D morphologies of several hundred species of mantises. We are creating a 3D morphology by using micro dissection, micro CT imaging to construct our 3D biomechanical model. We found the attachment points of the ligaments and muscles from a Tenodera forearm and have constructed a 2D biomechanical …
Structure Of Clostridium Perfringens Type Iv Pili, Alexander R. Meyer
Structure Of Clostridium Perfringens Type Iv Pili, Alexander R. Meyer
Honors Theses
Type IV pili (T4P) are thin, hair-like bacterial appendages composed of protein subunits polymerized into a helical fiber. T4P perform diverse functions such as host cell adhesion, biofilm formation, natural competence, and twitching motility. While T4P are well characterized in Gram-negative bacteria, they have more recently been found in Gram-positive bacteria as well. In this work we aimed to solve the crystal structure of the type IV major pilin protein PilA2 from Clostridium perfringens, the predominant pilus subunit which makes up about 99% of the pilus fiber. We report expression, purification, and crystallization conditions which are sufficient for X-ray …
