thickness transition of melt-crystallized polybuten-1 tetragonal phase: configurational change in chain folding

Motoi YAMASHITA

Frontiers of Chemical Science and Engineering 2009, Volume 3, Issue 1,   Pages 26-32 doi: 10.1007/s11705-009-0002-2

Abstract: Chain folding free energy determined from the low supercooling range is larger than that determinedPossible mechanisms for the transition are discussed taking account of entropy of chain folding directions

Production of rhamnolipids-producing enzymes of

Kata Kiss,Wei Ting Ng,Qingxin Li

Frontiers of Chemical Science and Engineering 2017, Volume 11, Issue 1,   Pages 133-138 doi: 10.1007/s11705-017-1637-z

Abstract: Rhamnolipids are a class of biosurfactants that have a great potential to be used in industries. Five proteins/enzymes, namely RhlA, RhlB, RhlC, RhlG and RhlI, are critical for the production of rhamnolipids in . Four of the 5 proteins except RhlC were successfully over-expressed in and three of them (RhlA, RhlB and RhlI) were purified and obtained in milligram quantities. The purified proteins were shown to be folded in solution. Homology models were built for RhlA, RhlB and RhlI. These results lay a basis for further structural and functional characterization of these proteins to favor the construction of super strains for rhamnolipids production.

Computation of the protein molecular mechanism using adaptive dihedral angle increments

Mikel DIEZ, Victor PETUYA, Mónica URIZAR, Erik MACHO, Oscar ALTUZARRRA

Frontiers of Mechanical Engineering 2013, Volume 8, Issue 1,   Pages 104-108 doi: 10.1007/s11465-013-0360-9

Abstract:

Protein motion simulation is still a troublesome problem yet to be solved, especially due to its high computational requirements. The procedure presented in this paper makes use of the proteins’ real degrees of freedom (DOFs). The procedure makes no use of any intermediate energy minimization processes that may alter the motion path or result in very high computational cost requirements. In order to reduce the computational cost, presented algorithms make use of the balls and rods approach for protein structure modelization. Also, structures are normalized in order to minimize inaccuracies introduced by experimental methods, providing a more efficient but still accurate structure for motion simulation.
