CARF promotes spermatogonial self-renewal and proliferation through Wnt signaling pathway.

Collaborator of ARF (CARF) regulates cell proliferative fate through both p53-dependent and -independent mechanisms. Recently, we reported a new function of CARF as a positive regulator of Wnt signaling. Despite these findings, the physiological function of CARF has not been well studied.

Bacillus subtilis alkaline phosphatase IV acquires activity only late at the stationary phase when produced in Escherichia coli. Overexpression and characterization of the recombinant enzyme.

The availability of recombinant monomeric alkaline phosphatase (AP) is highly desirable in analytical applications involving AP fusion proteins. The cobalt-dependant alkaline phosphatase IV from Bacillus subtilis (BSAP), which was reported to be strongly monomeric, was overexpressed in Escherichia coli using pET autoinduction system as a cytoplasmic protein without export signal sequence. After 1 day of growth, when the E.

Development of a whole-cell biocatalyst with NADPH regeneration system for biosulfoxidation.

A formate dehydrogenase gene (fdh) originated from Candida boidinii was co-expressed in E. coli BL21 (DE3) with the cyclohexanone monooxygenase gene (chmo) cloned from Acinetobacter calcoaceticus NCIMB 9871. The co-expression system was then used as a whole-cell biocatalyst to synthesize chiral phenyl methyl sulfoxide (PMSO) from thioanisole (PMS) and the reaction conditions were investigated.

2-[(E)-2-(Benzyl-idene-amino)-eth-yl]-3',6'-bis-(diethyl-amino)-spiro-[isoindoline-1,9'-xanthen]-3-one.

In the title compound, C(37)H(40)N(4)O(2), the xanthene and spiro-lactam rings are almost planar, with r.m.s.
