    摘要: Described is a novel process for the introduction of an organic acyl radical selectively at the nitrogen atom of the amino group of desferrioxamine B or of a partially O-acylated derivative thereof. It comprises treating a derivative of desferrioxamine B, in which the amino nitrogen and the hydroxy oxygen of at least one of the hydroxamic acid groupings carries an organic silyl group, with an organic acylating agent and then removing the silyl groups present. The novel N- and O-silylated starting materials can be manufactured, preferably in situ, by reacting an appropriate derivative of desferrioxamine B that has at least one hydroxy group and the amino group in free form, with an organic silicon halide.

    摘要: An error processing circuit for a receiving location of a system for transferring binary data in the form of pulse sequences, wherein the system has a number of receiving locations connected via a double-line bus having a first line and a second line. The circuit includes a data output, a decoder having three decoder outputs, of which a first decoder output associated with both lines delivers a first decoder output signal dependent on the difference between the potential values of both lines, a second decoder output associated with the first line delivers a second decoder output signal dependent on the difference between the potential value of the first line and a first mean potential value, and a third decoder output associated with the second line delivers a third decoder output signal dependent on the difference between the potential value of the second line and a second mean potential value. A line condition detector circuit detects error-free line conditions, line errors of the first line, and line errors of the second line, depending on the decoder output signals, and changeover control signals can be delivered to a changeover switch to deliver properly decoded data, depending on the particular detection result.

    摘要: A process is for preparing O-acetylserine, L-cysteine and sulphurous compounds derived therefrom using feedback-resistant serine acetyl transferases. In comparison with the wild-type enzyme, these serine acetyl transferases have reduced sensitivity to the inhibitor L-cysteine and a protein sequence which, in comparison with the wild-type enzyme, displays at least one mutation or deletion. The process has a mutation which lies in the sequence region of the amino acid in position 97 up to and including the amino acid in position 273 or the deletion lies in the carboxy terminal sequence region as from the amino acid in position 227, position 1 being the starter methionine of FIG. 5 (SEQ ID NO:1) and the mutation from Met to Ile in position 256 being excluded.

    摘要: A device for selection of address words, each having n bit locations and serving for addressing m different receiving locations of a digital communications apparatus, comprising a digital acceptance device via which address words can be selected which are acceptable for the particular receiving location in consideration. The acceptance device includes an address word segmenting device through which each address word received by the receiving location is subdivided into s address word segments with b segment bit locations each, wherein b=n/s and n is an integral multiple of s, a decoder having a decoder input accepting the bit pattern of the address word segment of the particular address word being examined for acceptance, and having a decoder output at which, for each of the possible segment bit patterns, a decoder output bit pattern representing only this segment bit pattern is available. The device also includes s filter registers associated with one of the address word segments each, for storing filter register bit patterns, a comparison circuit through which the decoder output bit pattern can be compared with the contents of the associated filter register, the output providing an examination result signal which is either a conformity signal or a non-conformity signal. The device also includes an evaluation circuit, that delivers an acceptance signal only when a conformity signal has been present at the output of the comparison circuit for each address word segment of this address word.
