You can use the $view widget, like this: <$view field="catalase" />
Alternatively, you can use *transclusion* syntax, like this: {{!!catalase}}.
The difference is that the $view widget will display the field value as
plain text, while the transclusion syntax will parse the field value as
wikitext, so it can contain other formatting syntax within the value of the
field,.

To automatically generate a list of all fields in a tiddler, you can use
the $list widget with the fields[] filter operator, like this:
<$list filter="[<currentTiddler>fields[]] -[[title]] -[[text]] -[[tags]]
-[[created]] -[[modified]]" variable="fieldname">
<<fieldname>> = <$view field=<<fieldname>> /><br>
</$list>
Notes:
* The fields[] operator returns ALL fields of the current tiddler,
including the standard fields that exist in every tiddler (title, text,
tags, created, modified). The example filter above removes those specific
field names so that only your "user" fields are output.
* The example uses the variable="somename" parameter to hold the matching
field name so that the <<currentTiddler>> value remains unchanged inside
the $list widget. This is needed so that the $view widget will reference
the current tiddler in which the $list widget occurs.
