Every 10th residue is labeled with the residue number as a subscript when showing 3-letter residue code (divided by 10, i.e. residue 120 is labeled with 12) or as a small tick mark when showing 1-letter code. The feature can be turned off Setup. Use the 1/3 button in the toolbar to switch between 1- and 3- letter code.
Cross-linked residues: Residues that are cross-linked, typically cysteine residues (see B-3).
Net charge: The theoretical charge of the protein at pH 2.0, 7.0 and user-selected pH (Setup).
A5 The leftmost panel shows the total mass of the protein in Daltons. The button next to it shows whether it is the average mass (Av. – blue) or monoisotopic mass (Mo. – red). You can change the mass type by clicking on the Av./Mo. button.
The next two panels from the left can show either of two states:
A6 If no peptide is selected the mass of the amino acid under the cursor (i.e. the residue mass + 18 Da) will be displayed in the left-hand panel and the right-hand panel will show the residue number (if the protein is a multi-chain protein, the first chain will be labeled ‘a’, the second ‘b’ etc (i.e. 80b is residue number 80 in the second chain counting from the N-terminus).
以上显示的，可以有多种配置方式：
显示1个或3个字母
平均质量/单同位素质量
固定残留物宽度
带有序列信息的提要栏
显示二硫化物桥、改性残留物等
通过**显示部分序列，您可以轻松获得给定肽的质量。为了便于导航，您可以使用特定颜色的残留物（提供三种不同颜色和下划线）。大多数设置可以很*地在系统设置框中预先设置。
科学软件网不定期举办各类公益培训和讲座，让您有更多机会免费学习和熟悉软件。
