چکیده

The title compound, C(51)H(78)INO(12), contains a 29-membered ring incorporating amide, lactone and ester groups. It contains a total of 15 stereogenic centres. In the crystal, mol-ecules are linked by O-H⋯O hydrogen bonds, forming C(8) chains propagating in [100]. A weak intra-molecular O-H⋯O inter-action also occurs.

1-De­oxy-l-mannitol (6-de­oxy-l-mannitol or l-rhamnitol)

The crystalline form of 1-de-oxy-l-mannitol, C(6)H(14)O(5), exists as an extensively hydrogen-bonded structure with each mol-ecule acting as a donor and acceptor for five hydrogen bonds. There are no unusual crystal-packing features; the absolute configuration was determined from the use of 6-de-oxy-l-mannose (l-rhamnose) as the starting material.

In the crystal structure of the title compound, C(27)H(27)NO(5)S, the pyran-ose ring adopts a (4)C(1) chair conformation with puckering parameters Q = 0.639 (2) Å, θ = 174.11 (18) and ϕ = 256 (2)°. The presence of the 2,3-trans-oxazolidinone fixes the conformation of the pyran-ose ring. The phenyl group attached to the S atom and the benzyl group bonding to the N atom are each disordered over t...

Distinct functions of eukaryotic translation initiation factors eIF1A and eIF3 in the formation of the 40 S ribosomal preinitiation complex.

We have used an in vitro translation initiation assay to investigate the requirements for the efficient transfer of Met-tRNAf (as Met-tRNAf.eIF2.GTP ternary complex) to 40 S ribosomal subunits in the absence of mRNA (or an AUG codon) to form the 40 S preinitiation complex. We observed that the 17-kDa initiation factor eIF1A is necessary and sufficient to mediate nearly quantitative transfer of ...
