    The aim of present study is to investigate maternal PIVKA-PC and PIVKA-11 levels during early postpartum period and their correlation with estradiol (E_2) levels. Study subjects were 23 puerperal women without any medical complications or previous history of VTE (venous thromboembolism). Blood was sampled on the day 0, 1, and 2-3^<rd> postpartum day, and we measured protein C (PC) antigens & activity, PIVKA-PC, PIVKA-11, and E_2. The PIVKA-PC level in total PC was 10〜20% throughout the postpartum period. Compared to PIVKA-11 level, it's level was strikingly high. Moreover, significant difference in PIVKA-PC levels among delivery modes and a considerable correlation between PIVKA-PC and the declining ratio of E_2 (r=0.416) were observed. The reason for increased risk of VTE during early postpartum period remains unclear. The current study suggests that a high PIVKA-PC plays an important role in the mechanism of VTE.

    Three cysteine desulfurases-IscS, CsdA, and SufS-of Escherichia coli can transfer sulfur from L-cysteine to the C-terminal carboxylate of the smaller subunit of molybdopterin synthase to yield a thiocarboxylate group in a defined in vitro system for the generation of the dithiolene group of molybdopterin from precursor Z, which is an oxygen-sensitive tetrahydropyranopterin and the immediate precursor of molybdopterin in molybdenum cofactor biosynthesis. In this study, we report that an iscS-deletion strain of E. coli accumulates compound Z, a direct oxidation product of precursor Z, to the same extent as a ΔmoaD strain. In contrast, analysis of the content of compound Z in ΔsufS and ΔcsdA strains revealed no such accumulation. These findings suggest that IscS is the primary sulfur-donating enzyme for the generation of the thiocarboxylate of molybdopterin synthase in molybdopterin biosynthesis.
