On the tertiary structure of tropomyosin tactoids

Biochemical and Biophysical Research Communications, 1975
Abstract Correlation of tropomyosin amino acid sequence with uranyl acetate stained magnesium salt tactoids has been carried out by a computer graphic technique. Contrary to some previous suggestions, the results seem to indicate that there is no chain stagger within the molecule and the molecules are aligned with 178 ± 2 residue overlap in ...

On the tertiary structure of satellite DNA

Biochimie, 1992
The primary structure of the Citrus ichangensis satellite DNA repeating unit has been estimated. The repeat is 181 bp long and contains four pentanucleotides of adenine residues. Oligomer forms of the stDNA repeating unit were detected by a partial hydrolysis of the C ichangensis stDNA by BspI restriction endonuclease.

Serpin tertiary structure transformation

Journal of Molecular Biology, 1991
Previous crystallographic analyses have demonstrated that proteolytic cleavage of the serpins can result in a dramatic transformation of their tertiary structure. Some 16 residues on the amino terminal side of the cleavage site are inserted into a large beta-sheet to become a central strand, separating the two cleaved residues by about 70 A.

A model for the tertiary structure of tRNA

Biochemical and Biophysical Research Communications, 1973
Abstract A model for tRNA is described which has as its basic structural mode a four stranded RNA helix, formed by pairing two stems respectively from the four ubiquitous arms of the clover-leaf secondary structure. The relation of the model to biochemical and crystallographic data on tRNA is considered.

Secondary and Tertiary Structure of Apolipoproteins

1988
The advent of these and other high-powered techniques for the detailed study of apoLP organization will allow us to obtain a high resolution picture of apoLP conformation both in solution and on native lipoprotein particles.

Unfolding of tertiary structures of proteins

International Journal of Peptide and Protein Research, 1984
The unfolding pathway of lysozyme was investigated by carrying out the computer simulation. Taking into account the simultaneous change of both the dihedral angles ø and of a residue, we explore the detailed features of the conformational energy profiles. The triangle distance map shows that the lysozyme molecule is divided into three domains, 1–40, 41–

Computing tertiary structures of proteins

Journal of Protein Chemistry, 1990
Using only data on sequence, a method of computing a low-resolution tertiary structure of a protein is described. The steps are: (a) Estimate the distances of individual residues from the centroid of the molecule, using data on hydrophobicity and additional geometrical constraints. (b) Using these distances, construct a two-valued matrix whose elements,

Maturation of Tertiary Lymphoid Structures

Tertiary lymphoid structures (TLS) are organized collections of B and T lymphocytes that arise in nonlymphoid tissue in response to chronic, unresolved inflammation. TLS have structural and functional similarities to germinal centers found in lymph nodes and are believed to support the establishment of lymph node-like adaptive immune responses at local

Tertiary Structure Prediction

1989
The polypeptide chain of globular protein is linear, but the three-dimensional of tertiary structure is quite contorted. This was apparent from the first crystallographic determination of the structure of a protein by Kendrew et al. (1960). The contortion arises because of the need to satisfy a multitude of conflicting interactions: the hydrogen ...

Modeling of Tertiary Structures

1995
Preceding chapters, but particularly Chapters 6–9 (covering methods, software packages, data, and secondary-structure predictive procedures), provide the basis for the discussion of specific details and practical applications to be presented in this and following chapters.
