How to convert .sbgn glyph ids to protein Identifiers

[nvelden]

I downloaded the SBGN file for pathway R-HSA-400511 from the reactome website. Is there anyway that I can convert the glyph id to there associated protein or compound id?

....
 <glyph class="process" id="reactionVertex_400459_16">
            <label text="Signal peptidase hydrolyzes preproGLP-1 to proGLP-1"/>
            <bbox w="12.0" h="12.0" x="316.0" y="297.0"/>
            <port id="reactionVertex_400459.1" x="321.0" y="313.0"/>
            <port id="reactionVertex_400459.2" x="322.0" y="293.0"/>
        </glyph>
        <glyph class="simple chemical" id="entityVertex_70115_38">
            <label text="Glc"/>
            <bbox w="35.0" h="30.0" x="18.0" y="878.0"/>
        </glyph>
        <glyph class="complex" id="entityVertex_264960_18">
            <label text="Signal Peptidase"/>
            <bbox w="125.0" h="24.0" x="459.0" y="244.0"/>
        </glyph>
        <glyph class="omitted process" id="reactionVertex_400509_42">
            <label text="Glucose-dependent Insulinotropic Polypeptide is secreted from intestinal K cells"/>
            <bbox w="12.0" h="12.0" x="762.0" y="780.0"/>
            <port id="reactionVertex_400509.1" x="767.0" y="796.0"/>
            <port id="reactionVertex_400509.2" x="768.0" y="776.0"/>
        </glyph>

pathwayCommons offers a mapping table with each glyph id and their associated uniprot id. Is there anything like this for Reactome?

 Uniprot                                                                     pathwayCommons
