Plasma fibronectin was chemically modified by 4-maleimido-2,2,6,6-tetramethylpiperidinooxyl (maleimide spin label). Only the free sulfhydryl groups of plasma fibronectin were modified by the label under the experimental conditions. The ESR spectrum o

Human plasma fibronectin exists in circulation in multiple molecular forms that are distinguishable by SDS-polyacrylamide gel electrophoresis (zone I, approx. 450 kDa dimers; zone II, 190-235 kDa; Zone III, 146-175 kDa). (Chen, A.B., Amrani, D.L. and

Human plasma fibronectin has been investigated by electron spin resonance (ESR) spin-label methods in conjunction with circular dichroism (CD) and sedimentation techniques to investigate its structure and flexibility in solution. The buried sulfhydry

The infrared and optical rotatory dispersion spectra of l -serine polypeptides have been studied. Infrared spectra of high molecular weight poly- l -serine show that the polypeptide exists in the β structure in the solid state. ORD‡ spectra obtain

The local environment of the free sulfhydryl groups in plasma fibronectin has been investigated by ESR techniques using a series of maleimide spin labels, varying in chain length between the maleimide and nitroxide free radical groups. Chemical modif

Fibrinogen has been modified proteolytically by a crude bacterial enzyme to produce highly ordered microcrystalline and crystalline forms (see also Tooney & Cohen, 1972 ; Cohen & Tooney, 1974 ). We present here a description of preparative methods, a

We have examined the interaction between heparin and human plasma fibronectin using electron spin resonance (ESR) spin label methods. The titratable sulfhydryl groups of plasma fibronectin were modified with a maleimide spin label [ Lai and Tooney (1

The synthesis of polymers containing O-tert-butyl-L-serine, O-tert-butyl-DL-serine, L-serine, and DL-serine is reported. The N-benzyloxycarbonyl-(L or DL)-serine benzyl ester was used to synthesize the corresponding N-benzyloxycarbonyl-O-tert-butyl-(

Fibrinogen forms microcrystals after cleavage with an enzyme from Pseudomonas. Electron microscope images reveal a close relation between these structures and fibrin. The results support the view that no major intramolecular rearrangement occurs in t
