Research works carried out by S.Y.Suieymanov basically focus on the study of the structural - molecular organization and topography of pigment - protein complexes of thylakoid membranes of the higher plants (spinach, wheat), regulation of their formation in chloroplasts. He is leading specialist in the field of biochemistry, biophysics and plant physiology. Through research works conducted by him the structural and molecular organization of thylakoid membranes of chloroplasts has been studied and topography of chlorophyll - protein complexes was modeled and principles of formation in plants have been determined. The studies resulted in significant findings including:

• It was found out that lipoprotein fraction of chloroplasts presents the sum of protein components of thylakoids. Peptides, lipids, and carbohydrates strongly linked to an protein part (apoprotein) of lipoprotein membranes was found at all stages of
  chloroplasts formation.

• By comparative research thylakoid gran and stroma of wheat ohluroplasts it was revealed, that they differ by spectral properties, a set of forms of chlorophyll, polypeptide structure and the organization of chlorophyll - protein complexes. Six chlorophyll-proteins were revealed for thylakoid gran, but four for thylakoid stroma.

• The analysis of proteins of thytakoid membranes of wheat genotypes resistant and susceptible to drought has shown that    under water stress resistant wheat variety majority of   Chl forms    - mainly parallel, but Chi forms at    648 and 656 nanometers - mainly perpendicular.

• For the first time both in light-harvesting, and in antenna    complex of   PS I presence of three Chi forms were revealed at 648, 651 and 656 nm with identical character of their orientation which would testify to a generality in the organization of forms of a chlorophyll in these complexes.

• It is shown, that in greening process bleached out wheat sprouts    in the    spectrum of fluorescence (77    ) the strip at 727 nm (describing nucleus PS I), is completely -wave area up to 740-742 nm, that clearly shows light-driven light-harvesting complex (LHC I.) and    its assembly with nuclear complex PS I.

• It was revealed, that specific inhibitor    transcriptions on 70 S ribosome chloroplasts - lyncomycin blocks synthesis of apoprotein    700 with molecular weight 72 kD , assembly Chi of    -protein C     1 and synthesis of polypeptides 48: 43,5 and 32 kD belonging to complex PS II. Thus reaction center Chl forms (PS) PS U disappear at 683 nm and PS I at 690, 696 and 705 nm. At the same action cycloheximide - inhibitor translation on 80 S ribosomes of cytoplasm in reduction of polypeptides in light-harvesting complex in the field of 29,5-22 kDa and in    reduction contents of the basic forms of a chlorophyll.
