1. Amino-acid sequencing is limited to smaller molecules, for example the endogenous opioid met-enkephalin with a molecular weight of 573.

2. The amino-acid sequences were aligned on the basis of structural superpositions.

3. Amino-acid residues that are completely conserved are shown in bold type.

4. Both of these non-conserved amino-acid substitutions would have highly detrimental effects on the catalytic function of the putative protein-tyrosine kinase.

5. Based on nucleotide sequence and amino-acid sequence comparisons, coding segments 7 and 8 seem to represent a partial internal gene duplication.

6. The proteins differ in amino-acid composition from one species to another but those of related species show some resemblances.

7. Firstly, cats need an amino-acid called taurine to prevent them from going blind.

8. The content ratio of basic and acidic amino-acid in the enzyme is similar to that of yeast.

9. Using the amino-acid pair predictability to quantify 3874 neuraminidases of influenza A viruses, we analyzed their evolutionary trend and compared with the change in global temperature since 1918.

10. Amination reaction of amino-acid with C60 led to water soluble amino-acid C60 derivatives.

11. Sichuan Mohair's total amino-acid content is 76.19%(based on absolute dry weight), 22.02% lower than that of northern Shaanxi Mohair's which is reported by Miss. Zhang Zhong-ying and Miss.

12. For example, by random folding, the amino-acid chain of the enzyme ribonuclease, a small protein, could adopt more than 1040 different shapes, which would take billions of years to explore.

13. It "denatures" protein molecules, so that their amino-acid chains unfold and digestive enzymes can attack them more easily.

14. This gene encodes a polypeptide of 211 amino-acid residues and belongs to a subgroup of the rice WRKY gene family that probably originated after the divergence of monocot and dicot plants.

15. Amino-acid content of F1 hybrids is genetically controlled by its parents.

16. Amino-acid amphoteric surfactant, a kind of green surfactant, has been used in leather industry more and more because of its innocuity, biodegradation and blending ability.

17. The rotatory direction of amino-acid can be predicted from its structure. further, the configurati...

18. At this stage the model was modified to the correct amino-acid sequence.

19. There are no missing amino acids. Dr Hahn has, however, found nine places along the amino-acid chain of killifish AHR where the link in the chain varies between individuals.

20. In addition, the positions of some of the proteins within the structure are approximate and detail is lacking on the amino-acid side chains hanging off the main structure.

20. Wish you will love and make progress everyday!

21. Dr Hahn has, however, found nine places along the amino-acid chain of killifish AHR where the link in the chain varies between individuals.

22. Differences were discovered between mammoth and African elephant in amino-acid positions that are otherwise invariant over several billion years of combined mammalian evolution.

24. The paws of the black bear in the northeastern China were analyzed for the amino-acid contents with 835 type automatic amino-acid analyzer.

25. Unfortunately, these black smokers are very acid, which prevents amino-acid stabilization, and thus the formation of organic molecules.

26. In one instance, the researchers found that adding just one specific amino-acid building block rendered the protein useless in protecting against HIV.
