The folding of cytochrome c(551) from Pseudomonas aeruginosa was previously thought to follow a simple sequential mechanism, consistent with the lack of histidine residues, other than the native His16 heme ligand, that can give rise to mis-coordinated species. However, further kinetic analysis reveals complexities indicative of a folding mechanism involving parallel pathways. Double-jump interr...

Cytochrome c(552) (PH c(552)) from moderately thermophilic Hydrogenophilus thermoluteolus exhibits stability intermediate between those of cytochrome c(552) (HT c(552)) from thermophilic Hydrogenobacter thermophilus and cytochrome c(551) (PA c(551)) from mesophilic Pseudomonas aeruginosa. To understand the mechanism of stabilization of PH c(552), we introduced mutations into PH c(552) at five s...

Drawing upon organizational culture and institutional theory, this study investigates how institutional pressures motivate the firm to adopt Internet-enabled Supply Chain Management systems (eSCM) and how such effects are moderated by organizational culture. The results of a survey of 131 firms suggest that the dimensions of institutional pressures (i.e., normative, mimetic, and coercive pressu...

Thermal stability was measured for variants of cytochrome c-551 (PA c-551) from a mesophile, Pseudomonas aeruginosa, and a thermophilic counterpart, Hydrogenobacter thermophilus cytochrome c-552 (HT c-552), by differential scanning calorimetry (DSC) at pH 3.6. The mutated residues in PA c-551, selected with reference to the corresponding residues in HT c-552, were located in three spatially sep...

Congress implemented the children’s component of the 551 program in 1974 in recognition that disabled children who live in low-income households are among the most disadvantaged of all Americans and therefore deserve special assistance. The cost of caring for a child with special needs is an especially heavy burden for families with limited resources. The intent of the 551 program is to reduce ...

OBJECTIVES Reduced susceptibility to extended-spectrum cephalosporins in Neisseria gonorrhoeae has, to date, been associated with three alterations: a mosaic penA allele encoding the penicillin-binding protein 2 (PBP2); A-del-mtrR, an adenine deletion in the mtrR promoter; and penB, comprising mutated alleles of PorBIb. In this study, we examined an association between reduced susceptibility to...
