<!-- Page Title: Hemoglobin -->
<h2>Introduction</h2>
<p>
    These scripts show the 1.74 Angstrom structure of human deoxyhemoglobin.
    (Based on 2hhb.pdb, Fermi et al. (1984) J.Mol.Biol. <strong>175</strong>:
    159-174)
</p>
<br>

<h2>Hemoglobin 1</h2>
<p>
    Hemoglobin is a tetramer (ribbons) and each subunit has a bound
    <span style="color:#E06633;"><strong>heme</strong></span> group
    (spacefilling).
</p>
<!-- JSMol Window Container -->
<div id="jsmolWindow1"></div>
<!-- UI Control Box -->
<div style="text-align: center;">
    <!-- give the button a right margin for spacing -->
    <button type="button" id="resetBtn1" style="margin-right: 10px;">Reset</button>
    <input type="checkbox" id="spinBox1"> Spin On/Off
</div>
<br>

<h2>&alpha; Subunits</h2>
<p>
    There are two <span style="color:green;"><strong>alpha</strong></span>
    subunits.
</p>
<div id="jsmolWindow2"></div>
<div style="text-align: center; margin-top: 10px;">
    <button type="button" id="resetBtn2" style="margin-right: 10px;">Reset</button>
    <input type="checkbox" id="spinBox2"> Spin On/Off
</div>
<br>

<h2>&beta; Subunits</h2>
<p>
    And there are two <span style="color:red;"><strong>beta</strong></span>
    subunits.
</p>
<div id="jsmolWindow3"></div>
<div style="text-align: center; margin-top: 10px;">
    <button type="button" id="resetBtn3" style="margin-right: 10px;">Reset</button>
    <input type="checkbox" id="spinBox3"> Spin On/Off
</div>
<br>

<h2>Hemoglobin 4</h2>
<p>
    Notice how tightly the four subunits interact with each other at most of the
    interface. However, there is a prominent hole down the middle of the
    molecule. Also, only the outer edge of the <strong>
    <span style="color:#909090;">heme</span></strong> is exposed to the solvent.
